## Snowflakes (B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e)

For discussion of other cellular automata.

### Snowflakes (B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e)

A rule so named for this common still life, which crystallizes from a simple seed:
x = 15, y = 7, rule = B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e3bo$b5o$bo3bo$2obob2o5bobo$bo3bo$b5o$3bo!

A c/2 glider can collide with a snowflake, pushing it back and creating a glider:
x = 21, y = 7, rule = B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e3bo$b5o$bo3bo13b2o$2obob2o12bo$bo3bo13b2o$b5o$3bo!

Feeding this reaction back into itself creates O(sqrt(t)) bounding box growth: (Credit: Danny)

A Z can push the snowflake back, creating a 90/180 degree reflector:
x = 19, y = 28, rule = B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e8bo$6b5o$6bo3bo6b2o$2bo2b2obob2o5bo$3o3bo3bo6b2o$o5b5o$8bo20$13b3o$13bobo!

I really like this rule! I see that Danny has taken the liberty of Catagoluing it: https://catagolue.appspot.com/census/b2ci3ai4c8s02ae3eijkq4iz5ar6i7e/C1

Guns exist for all periods greater than or equal to 34:

How would one search for a pull reaction that also reflects the glider? Other than that, this 2c/12 diagonal spaceship popped out of apgsearch: x = 4, y = 5, rule = B2ci3ai4c8/S02ae3eijkq4iz5ar6i7ebo$3o$3bo2$o2bo!

Pretty much all Z-based things can have each Z reduced to this 4-cell still life (don't know how it slipped past everyone, haha.):

Also, a fun smaller p18 completely unrelated to the one in the OP:
x = 13, y = 6, rule = B2ci3ai4c8/S02ae3eijkq4iz5ar6i7eb2o$2bo$o4bobo$12bo$10bo$10b2o! Various oscillators are on catagolue, but this one is my favourite.

It seems that interest has died off pretty soon. I still think this rule has great potential for engineered circuits.
Are there any snowflake-pull reactions?

Yes, despite the small and orthogonal p2 glider, its guns, eaters, stable reflectors and signal duplicators etc. it would be easy to construct complex patterns. Probably the audience are keeping in mind and in scope that there are even outer-totalistic Life-like rules without proofs for availability for arbitrary computations

The proofs of this are exactly the same as in Life and apply to all rules with guns and a clean annihilation reaction.

What I think is going on is that we're finding so many rules with dynamics similar to this rule that the threshold for lasting interest keeps being pushed higher and higher.
We build the oscillators, we construct the guns, we search for some ships, and we move on to the next challenge.

### Re: Snowflakes (B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e)

I did some soup search on several symmetries, but most extensively on D4_+1 and got some nice results.

Most importantly I found a new reflector (as part of an oscillator). Now we have 6 (of 2 general types) reflectors:
x = 43, y = 101, rule = B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e8$26b2o$27bo$26b2o4$29bo$31bo$30b2o$28bo$35b2o$35bo$35b2o$28bo$30b2o$31bo$29bo6$31b2o$31bo$30b2o$28bo$35b2o$35bo$35b2o$28bo$30b2o$31bo$31b2o5$29bo$27b5o3b2o$27bo3bo3bo$23bo2b2obob2o2b2o$21b3o3bo3bo$21bo5b5o$29bo10$29bo$27b5o3b2o$21bo5bo3bo3bo$23bo2b2obob2o2b2o$22b2o3bo3bo$27b5o$29bo8$29bo$27b5o$27bo3bo3b2o$23bo2b2obob2o2bo$21b3o3bo3bo3b2o$21bo5b5o$29bo10$29bo$27b5o$21bo5bo3bo3b2o$23bo2b2obob2o2bo$22b2o3bo3bo3b2o$27b5o$29bo! Most importantly, the new reflector(s) reflect(s) the glider colour preserving. Thus, this reflector allows many nice things. E.g. the p39+4N gun (above) can be made much smaller: x = 69, y = 114, rule = B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e5$52b2o$53bo$53b2o3$54bo$52b5o$52bo3bo$51b2obob2o$54bo4$54bobo$54b3o16$25b2o12b2o$16bo7bob2o10b2obo7bo$11bo13b2o12b2o$9b3o4bo32bo4b3o$9bo44bobo4$54bo$51b2obob2o$52bo3bo$52b5o$54bo3$53b2o$53bo$52b2o3$52bo3bo$49bo9bo$51bo5bo$50b2o5b2o$31bo$33bo$32b2o$30bo$38b2o$37b2obo7bo$38b2o$30bo17bo4b3o$32b2o19bobo$33bo$31bo2$53bo$50b2obob2o$51bo3bo$51b5o$53bo3$52b2o$52bo$54bo4$52bo3bo$49bo9bo$51bo5bo$50b2o5b2o2$30bo$32bo$31b2o$29bo$38b2o$37b2obo7bo$38b2o$29bo18bo4b3o$31b2o20bobo$32bo$30bo2$53bo$50b2obob2o$51bo3bo$51b5o$53bo3$52b2o$52bo$54bo!

But it also allows for small families of oscillators with adjustable an even period:
x = 90, y = 34, rule = B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e5$5b2o2b2o12b2o3b2o20b2o4b2o14b2o6b2o$5bo4bo12bo5bo20bo6bo14bo8bo$4b2o4b2o10b2o5b2o18b2o6b2o12b2o8b2o$2bo10bo6bo11bo14bo12bo8bo14bo$7b2o16b2o22b2o6b2o13b2o6b2o$8bo17bo22bo8bo13bo8bo$7b2o16b2o22b2o6b2o13b2o6b2o$2bo10bo6bo11bo14bo12bo8bo14bo$4b2o4b2o10b2o5b2o18b2o6b2o12b2o8b2o$5bo4bo12bo5bo20bo6bo14bo8bo$5b2o2b2o12b2o3b2o20b2o4b2o14b2o6b2o3$4bo6bo11bo7bo$6bo2bo15bo3bo$5b2o2b2o13b2o3b2o17bo10bo10bo12bo$3bo8bo9bo9bo17bo6bo14bo8bo$8b2o17b2o20b2o6b2o12b2o8b2o$9bo18bo18bo12bo8bo14bo$8b2o17b2o20b2o6b2o12b2o8b2o$3bo8bo9bo9bo16bo8bo12bo10bo$5b2o2b2o13b2o3b2o18b2o6b2o12b2o8b2o$6bo2bo15bo3bo17bo12bo8bo14bo$4bo6bo11bo7bo17b2o6b2o12b2o8b2o$50bo6bo14bo8bo$48bo10bo10bo12bo!

So we have p12+4N oscillators (one glider version), such as p10+4N oscillators (two glider versions), as we have many known p2, p4, p6, p8 oscillators, we have oscillators for all even periods.
However, combining it with the odd reflector (colour changing reflector), we get p37+4N oscillators (with 1 glider), and p35+4N oscillators (with 2 gliders):

Thus, we have oscillators for all odd periods larger than 33 and all larger periods oscillators are known. For small periods, we know oscillators for all periods (smallest known example listed until p50):

This allows now for ridiculously small oscillators of period p29+4N (2gliders shuttle, with population 14!) and p31+4N (1 glider shuttle):
x = 68, y = 37, rule = B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e4$21bo21bo$15bo3bo16bo4bo$19b2o20b2o$8bo13bo6bo14bo2$9bobo4bo13bobo4bo2$8bo13bo6bo14bo$19b2o20b2o$15bo3bo16bo4bo$21bo21bo11$11bo8bo26bo10bo2$4bo22bo12bo24bo2$5bobo4bo6bo4bobo14bobo4bo8bo4bobo2$4bo22bo12bo24bo2$11bo8bo26bo10bo!

So some of the minimal oscillators above, have a smaller version. Also some guns can be made smaller using this technology.

The upper one is p2, the other ones are stable. The p2 is very fast, the turning reaction requires only 4 ticks, so it allows for a p8 glider shuttle: x = 12, y = 13, rule = B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e4bo$2b5o$2bo3bo$b2obo$2bo5b2o$o5bo2bo$3o6b3o$2bo3bo4bo$2b2o5bo$7bob2o$5bo3bo$5b5o$7bo! EDIT2: As mentioned by danny for the synthesis of the 12 glider 2c/19 spaceship, it seems that synthesis of still lifes is hard, as no still life (except 1 single cell) can be created by two gliders.

We have 4 gliders for the p4 spaceship (the R) and 12 gliders for the c/6 (p12) diagonal spaceship.
3 gliders for a snowflake and a 1/2-snowflake which is optimal.
4 gliders for the 3/4 snowflake, 5 gliders (1G+1R) for the 4 cell eater, 6 gliders for the 5 cell eater (the Z) and 10 gliders for the carrier.
12 gliders for the 'extended' 3/4 snowflake, and 14 for the 7-bit still life (the W heptomino). 8 gliders for the second most common 7bit still life (point symmetric 4-bit still life). And 8 gliders for a quite complex still life: two stacked W.
Everything which requires more than 3 gliders might be improved.

This 90° R to G reflector in combination with the standard 90° G to G snowflake-reflectors and the 90° R to G converter can be used to construct any colour changing 90° reflector (the actual ones are colour preserving - this is also the reason the large repeat time of the splitter).

However, now the rule has lots of nice things:
- all stable colour changing 90° and 180° R and G reflectors,
- G and R guns of larger periods (G 33>=, R 40>=, also some smaller periods) and pseudo guns should be constructable for periods p>=21:
