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.

I never saw that edge gun before, where did you find it?

This reaction was posted by Tanner Jacobi here. It is based on the 180-degree reflector found by Arie Paap here.

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.

I want the entire collection of all 2c/5 ships There is no "entire collection", because there are too many 2c/5 ships to keep track of (likewise with c/3 and c/4). Most known elementary and elementary-based moving objects are contained in the following collections: jslife-moving , knightt results ,...

Adding another ship gave this: (c/4 diagonal puffer, p40) Wow! I think this is the first new c/4 diagonal period achieved since the rake constructions 14 years ago! I posted on the Discord yesterday my find that the existing stabilization of the c/4 diagonal puffer engine could be combined with a k...

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

My reasoning at the time was that fireship is the smallest known spaceship capable of pulling those tagalongs.

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. The look-ahead step accepts or rejects a new row by searching for a slight extension (if none is found, th...

I'm attempting to enumerate all width-10 odd-bilateral c/3 orthogonal spaceships with gfind (without repeating parts, of course.) gfind was not designed for this. Instead you would want to use knightt . In this case, however, the search has already been completed . I generally keep knightt results ...

Might as well reduce the bounding box without affecting the population:

This block pull is an example of a still life tagalong . Such tagalongs can typically work at multiple speeds. There are four known (1,0)c/p block pulling reactions (taken from here ): x = 66, y = 64, rule = B3/S23 6bo3b3o5b3o3bo16bo3b3o5b3o3bo$3b2ob5ob2o3b2ob5ob2o10b2ob5ob2o3b2ob5ob 2o$bob2obo5bobo...

Can there be an other-side fencepost for this? All I remember offhand is Sokwe's c/5 stabilization from 2013 That post only shows Hartmut Holzwart's stabilization (mine are two posts above). A more complete survey of those c/5 wickstretchers is given here . P12 searches are still very difficult. Or...
