Re: Oscillator Discussion Thread

Finished the near-miss It's really quite astounding that you pulled this additional TL hassler out of the aether. The spark here is a bit stronger, so it can be used to activate the block+pond reaction for another nice p26: x = 32, y = 40, rule = B3/S23 20bobobobo$19bob2ob2obo$17b3o7b3o$16bo4b2ob2o...

here's a reduced p6 HW emulator. Found with ofind but one may cut a row or two. That's amazingly compact! Only the top 8 rows are p6; the rest is p3.

Re: Small Spaceship Syntheses

By the way, this ship (27P4H1V1) is called "wings" in Nicolay Beluchenko's small ship collection. I was unable to determine where the name came from. The ship itself was discovered by Jason Summers on September 13, 2000 using gfind. It was found in the same search that found crab.

?????? but you included fireships pulling blocks

The maximum speed that zfind supports is c/2. I don't know the algorithm well enough to explain this limitation. That's not quite true. Searching for a 2c/3 in B2ac3ae/S1c2i3i works just fine.
