For instance, there's a nook in this forum where people of my age or so (including yours truly) discuss extremely large numbers.

Re: Synthesising Oscillators

One oscillator that seems to be missing from "hs21" is the Tumbler 16P14_j9d0d9j. Or am I looking in the wrong place? That is my fault; I forgot it in the list I originally sent. When I think of small oscillators, I often forget that one, because it's fairly unique; the next larger ones have 28 bits.

Re: Synthesising Oscillators

I found 129 erroneous apgcodes in the 808207 lines of text. Each erroneous apgcode represents the OR of two successive generations of an oscillator; this type of error seemed frequent with pseudo-p2s involving barberpoles. The errors are listed below, together with the correct oscillators I sussed ...

There needs to be a list of all p2s and p3s up to 21 bits available somewhere.
I have those. They aren't in APG format (which I presume would be the best ones) but I can convert them and post them somewhere. What would be the best place?

I wonder if it might not be a good idea to have Catagolue auto-generate syntheses for smaller p2s (and possibly other periods) as it already does for still-lifes?

Gliders hitting pre-blocks are the most common sources of LWSS and MWSS, and pre-blocks are extremely common in soups, so this is not really surprising or extraordinary.

Are there any P41 oscillators? Not yet. For many years, there were known oscillators of all periods except 19, 23, 38, and 41 (and only trivial 34s that combined independent p2 and p17 stators). With the recent discovery of the David Hilbert, period 23 has now been crossed off that list, but the ot...
