### Re: Reflectorless Rotating Oscillators (RRO)

So... does anyone have a table of loopabilities that are known? Or periods (of RROs only) that are known? Or both? I recently wrote a small script that checks the loopabilities. Recent matchpatt2 results gave plenty of loopabilities. I attached a csv of results of a single search, but there are man...

### Re: gencols: techniques

If I got it correctly gencols returns a list of interacting pattern. E.g. this is counted as 'collision' of 2 gliders in Life: x = 9, y = 4, rule = B3/S23 6b3o$2bo3bo$obo4bo$b2o! This is due to possible 2n, 2k and 2i (Hensel notation) neighbourhood. I did not dive deep into the gencols code, but is ...

### Re: Script request thread

The first one is false, the latter true. Is there a better way, for doing so? It's relatively straightforward like so (by the way, this assumes the pattern consists only of disjoint gliders): import lifelib lt = lifelib.load_rules('b3s23').lifetree(n_layers=1) x = lt.pattern('''x = 16, y = 13, rule...

Jeremy's Shinjuku project already has this functionality. I did not find a function that supports this functionality in Shinjuku.
