Is there a reason we have 14 pages for bipole extensions?

This morning, after coming back from holiday, I proved greycells/OffNeutronium/ExtendedLifeButNotAsGood omniperiodic. I'm quite happy with this result, especially considering the time I spent soup searching, and considering how close this rule is to Life - maybe some of the higher period oscillators...

That's a nice set of results, a shame they're all negative, but not too surprising. A few of them are duplicates of earlier results posted here, but it's good to have a summary of these higher period results in one place. Some of the previous results: 5c/11, w10; 3c/13, w7 Thanks.

I've spent the last month or so using ntzfind to search for low-width high-period ships, in hopes of finding the next Copperhead. Unfortunately there have been no positive results, but here are all the negative results: Speed - Asymmetric width - Odd width - Even width - Gutter width c/11 - 5 - 6 - ...

Thanks everyone, I'll remember to check pattern collections before posting next time. but the pattern file in my collection is dated 2000-04-14, so the synthesis is at least that old. It has three syntheses, from 24, 28, and 34 gliders respectively. 18, assuming the block+blinker takes 4 gliders: x ...

Found a funky looking P4 oscillator with Randcat:

That's a nice coincidence - Life's rulestring is B3/S23.

That's because 21-bit still lifes are surprisingly common, and so are not considered notable. I think the discoveries page contains still lifes greater than 32 bits, but I could be wrong there.

I'm surprised that nobody mentioned that the Catagolue has reached 30 trillion objects.
