I found a 5-in-a-row (6,24)c/870 spaceship: #C [(-33, 15, -106),(-33, 4, -114),(-33, -2, -42)] #C [[ X 12 TRACK 6/870 24/870 ]] x = 129, y = 23, rule = B3-jknr4ity5ijk6i8/S23-a4city6c7c 115bo$114b3o$113bo2b2o$69b2o42b4obo$56bo11bob2o42b2ob3o$55b4o8b2ob2o 47b2o$54bo4bo8b3o42b2ob2ob2o$48b2o3bo3bobo9bo...

Earlier this year I published the construction of x-in-a-row (3,12) oblique spaceships using copies of cloverleaf. Below is a review of two examples with annotation: #C [[ ARROWTRACK 3/1275 12/1275 ARROW 143.5 24.5 111.5 16.5 3.2 ]] #C [[ ARROWTRACK 3/1275 12/1275 ARROW 111.5 16.5 82.5 16.5 3.2 ]] #...

Partly off-topic, what about catagolue's all-common-names.txt?

FWKnightship's spaceship constructions in Harvest Moon (8c/97, 48c/160, 8c/25876 and 90c/450) definitely needs more appreciation.

i dunno if this was already known, here's a tiny rake i originally posted in rle copy/paste thread.

what about these guns?

Is there any reason not to read through the thread and check known patterns before asking?

This soup has a final population of 3362 cells

As I am writing, the megasized tabulation says that there are about 6 million soups of megasized_33h.

What exactly is so special about this October? We have seen a number of newcomers making many threads for OCA rules. Apart from this one , they ( 1 2 3 4 5 6 7 8 9 ) tend to have rather simple rule definitions and only a handful of objects to start a discussion with. Is this because more general thr...

Pay close attention to the outer zone of soups and many interesting things will be found.

xs17_0696kk8z3113 in 8G, down from 11G Let's go for the more expensive 17-cell still lives; I wonder if we can manage 17-in-13 or even 12 [fitting in the n-in-(n-5) scheme]. A fresh example: xs17_069la8oz2521 in 9G based on this soup (may be improved to 8G with a tricky 2-glider cleanup) x = 42, y ...

Ok, I do not understand what you mean. I'm trying to follow this tutorial: https://conwaylife.com/wiki/Tutorials/Your_first_Python_script Are you saying I have to somehow write the script in golly so that the script runs from golly? The tutorial mentions a python ide window but doesn't elaborate on...

Wow, I don't recall seeing any gun collection like that in 2-state non-totalistic rules before. c/6 orthogonal spaceships have tagalongs similar to the known c/3, and here they are infinitely extensible: #C [[ TRACK 0 -1/6 ]] x = 88, y = 77, rule = B3aeiry4eqtwz5acen6c/S1c2-kn3-akr4-aejw5-i6-n7 5b2o...

Some ship-still life interactions The snake as 180-degree reflector implies p(22+4n) shuttle when coupled with itself, or p(24+4n) shuttle with a p4 dot sparker. Only p14 and p18 left for even periods. (EDIT: the p12 gun can be two cells smaller) x = 119, y = 15, rule = B3aeiry4eqtwz5acen6c/S1c2-kn...

This p56 Julia-hassling-Julia oscillator grabbed my attention.

While a ship costs 3 gliders, a certain ship-and-glider combination still costs 3 gliders and catagolue has a synthesis that implicitly uses it: #C [[ GRID MAXGRIDSIZE 14 THEME Catagolue ]] #CSYNTH xs13_178czy8okc costs 4 gliders (pseudo). #CLL state-numbering golly x = 21, y = 6, rule = B3/S23 bo$2...

Finally I can make a contribution to the topic, although it is more adjustable slope glider rakes than spaceships. I found an explosive rule with a glider + 3×3 checkerboard collision that results in 2-barrelled 3c/(78+8n) diagonal rakes: x = 74, y = 14, rule = B3aeijn4w5qr7e/S23-eky4cnqyz5aknr6-ai7...
