Me neither. I did have a play around with apgsearch to try to find natural synthesis of block-on-eater, but nothing concrete so far.
There were about 20 occurences of block-on-eater in 2,000,000 soups. The majority were variants of this:
Code: Select all
x = 14, y = 16, rule = B3/S23
12b2o$12b2o$3bobo$3bobo$3b3o7$3o2$4bo$4bo$4bo!
but they don't look suitable because the blinker is one cell too far south and would interact with the snake.
Most other occurences were fairly wild but there was this one:
Code: Select all
x = 16, y = 16, rule = B3/S23
4bobo3b3obo$bob4ob4obo$o2bobob2o4bobo$b3ob2o3bobob2o$2obobob4o3bo$2b2o
3bobobob2o$2o2b4obobob3o$obo2bo3bobo2bo$b5obobo2b2o$3obob2o2b6o$2ob2ob
3ob6o$3o5b2o2b2o$2obob4ob3o2bo$ob3obobob2o$2o3b3obo4bo$2b3obob4obo!
that hints at the following synthesis:
Code: Select all
x = 20, y = 13, rule = B3/S23
bo$2bo14bo$3o14bobo$14bo2b2o$8b2o5bo$7bo2bo2b3o$6b2o2bo$7b2obo$8bo$9bo
2b2ob2o$12bo3bo$13bobo$12b2ob2o!
Also I found that block-on-eater is easily obtained from block-on-beacon:
Code: Select all
x = 7, y = 13, rule = B3/S23
5bo$4bo$4b3o2$o$b2o$2o3$2o$2o$2b2ob2o$2b2ob2o!
and that block-on-beacon is _very_ common. Almost as common as MWSS. Unfortunately _every_ soup I looked at (maybe 50 of them) contained this predecessor:
Code: Select all
x = 6, y = 5, rule = B3/S23
o$3o$3o2$3b3o!
which is not suitable for the same reason as the pi + 2 blinker pattern above.
I found a single instance of block-on-intergral-sign but it was completely wild.
The initialisation of my decompositions dictionary in apgsearch reads:
Code: Select all
decompositions = {"xs18_3pq3qp3": ["xs14_3123qp3", "xs4_33"],
"xs11_0gbrz23": ["xs11_0gbrz23"],
"xp2_rbzw23": ["xp2_rbzw23"],
"xs13_330354ko": ["xs13_330354ko"]}
and I added these to the commonnames dictionary:
Code: Select all
"xs11_0gbrz23": ("block-on-eater", 50),
"xp2_rbzw23": ("block-on-beacon", 40),
"xs13_330354ko": ("block-on-integral-sign", 60)}
if anyone wants to try their luck.
