### Re: Oscillator Discussion Thread

Here is a period 644 oscillator which demonstrates an interesting old reaction.

The reaction is an input glider hitting three blocks arranged in the corners of a rectangle, resulting in an output glider and the same arrangement of three blocks (but flipped). The oscillator performs the reaction twice during each period. Moving pairs of the snarks further away can increase the period by any multiple of 8. The period can be reduced to 628 if the eaters of some pairs of snarks are welded together. Oscillators using the reaction were possible before, but using snarks makes it simpler and smaller. (It is fortunate that the input and output gliders of the reaction have the same color, otherwise larger glider reflectors would have been needed.) Can someone please tell me who found the reaction and when? Thanks.

The domino spark produced by the p4 oscillator inhibits every other output glider. Other period sparkers might work similarly to create occasional holes in the stream. My collection is very old so there might be a smaller p4 sparker that works here. This is the first p30 or p46 gun I know of where a p4 oscillator can successfully thin its stream. BCNU, -dbell dbell Posts: 45 Joined: June 27th, 2013, 12:47 am ### Re: Oscillator Discussion Thread The spark on Tanner's period 46 oscillator is very similar to the one on the period 15 pentadecathlon, so it can perturb things in similar ways. For example, it can reflect a glider by 180 degrees in the same way. So you can create a glider relay between these two oscillators (but the separation is pretty large). x = 209, y = 182201b8o201bob4obo201b8o1554boo5bo28boo5bobo25bobo6boobboo23bo10boo7o3o7boo3bo6boobbobo7bobboo6boo10boobboobbo3b3o5bo8boo9bo6b3o6bo!

Thanks! that does help. I am now pretty sure I remember being disappointed that the 3-block catalyst only shifts and does not reflect the glider, and I don't know if I ever tried to do anything else with it.

The following interesting oscillator showed up in a soup 2 days ago. Its core is supported by 4 mutated molds: http://catagolue.appspot.com/object/xp4_8kicjnty0tnjcik8z4aicjrfy0frjcia4zy0111y0111/b3s23
It forms from four mutated bakery predecessors surrounding an interchange predecessor, so it might be easy to synthesize:

### Re: Oscillator Discussion Thread

I found an old period 160 glider duplicator reaction in my files which used period 8 reflectors to support the reaction in a loop. Unfortunately, the duplicated gliders are on a close path to the others, and so usually have to be deleted.

I upgraded the reaction to use snarks instead of the reflectors, and this is shown here. Also, for a bit of added interest, I used some of the extra gliders for kickbacks to make a period 640 glider relay.
The separation of the two halfs can be adjusted by multiples of 40 cells to change the size and period of the relay.

Previously, I managed to build a glider gun from the glider duplicating reaction by adding a pi heptomino glider reflecting reaction to extract the inconvenient extra gliders. This is shown below, and also shows how the p8 reflectors were used. #C Period 160 glider gun built using period 160 glider duplication#C reactions and a pi based glider reflection reaction.#C David I.

To make a modern version of this without any foreign oscillators, snarks can probably be used to eliminate all the p8 reflectors, and a catalyst can eliminate the period 5 sparker, but I don't see offhand how to avoid the p8 blocker.

Has this smiley interaction been discovered? ... Interesting. I hadn't tried different geometries; I just cloned the P80 and replaced the fumarole with a pentadecathlon to make the P240 (an its synthesis works for this one too, just by moving the pentadecathlon gliders one space). Sadly, this unusual spark trick doesn't work with a fumarole. I hadn't seen the smileys either. There seem to be two ways smileys can share sparks, although I don't see how to synthesize either one of them, as none of the known smiley syntheses edge shoot one. Smiley+pentadecathlon also works, for a true P120. mniemiec Posts: 934 Joined: June 1st, 2013, 12:00 am ### Re: Oscillator Discussion Thread A new minimal 74p78: x = 18, y = 31, rule = 23/34b3o2$6bo$6b2o$5bo$8bo$4bo3bo$9b2o$2o2b3o5bo$2o5bo4b2obo$7bo3bo3bo$7bobo5bo3$6b2o$6b2o$11b3o2$12bo2$7b2o2b3o2b2o$7bobob3obobo$8bo7bo2$8bo7bo$7bobob3obobo$7b2o2b3o2b2o2$12bo2$11b3o! which is T-nosed p6 on 34P13.
