Re: Small Spaceship Syntheses

Now, as far as I know, the two smallest un-buildable spaceships are the 29- and 30-bit c/3 ones. Indeed. I think the following are all of the known ships with no known synthesis up to 36 cells: x = 158, y = 213, rule = B3/S23 29bo$27b2o$27b2o$29bo$27bo$obobo3bobobo13b3o$26bo$4bo3bo3bo12b2o$28bo$ ob...

Re: Spaceship Discussion Thread

seven period shifts comibined with some spatial shifts. Here is a clean p14... Interesting idea, although the period is 26. The fuse travels at 6c/13. The blinkers can also be out of phase, allowing more combinations: x = 29, y = 188, rule = B3/S23 7b3o9b3o$7bobo9bobo$6bo2bo9bo2bo$6bob4o5b4obo$4b2o...

Re: Spaceship Discussion Thread

Catagolue erroneously reports a p182 puffer. It's actually the p14 3c/7 blinker puffer followed by a 12c/26 fuse: x = 29, y = 188, rule = B3/S23 7b3o9b3o$7bobo9bobo$6bo2bo9bo2bo$6bob4o5b4obo$4b2o4bobo3bobo4b2o$5b3ob 2obo3bob2ob3o$3bo8bo3bo8bo$3bobo2b2obo5bob2o2bobo$2bo3b2o4bo3bo4b2o3bo $3bobo5bo5bo...

P14 3c/7 blinker-pair puffer found by Dylan Chen, the lowest-period 3c/7 linear-growth mechanism so far Very nice! Based on this and a suggestion by Hartmut Holzwart to look at different ways to stabilize the p28 wave, I was inspired to find these new puffers (periods 28 and 84): x = 284, y = 256, ...

When I try this, the search quickly widens to well outside of a reasonable search width. I'm going to guess that it's because of the spaghetti monsters.

That's a good partial result! I suspect that playing around with adjusting and tapering the rotor search area should yield a complete sparker.

Nothing very interesting here. I just rearranged some of the parts to reduce the size of the 3c/7 p21 ship and p84 rake.

Amazing! What are the the tools you used for finding these? Assuming you're talking about the rake, I didn't use any sophisticated tools. I just tried various spaceship placements by hand in Golly, so my search was not thorough. I'm still hopeful that someone will find a period-21 rake. Edit: Chris...
