The immediate predecessor seems to be a mirrored version of block+blinker+small piece of junk, but in any case a synthesis doesn't seem like it would be too difficult.

Well, those pre-TLs make a pre-interchange, so there are a lot of options to check. Really I think there are only 87 that include the right population sequence, though.

Unfortunately the current version of the script can't separate different orientations of the pre-TLs -- we should probably rewrite it to use apgcodes or some other hash value that notices differences in orientations of subpatterns. But it looks like all of these have two pre-beehives for a predecessor, or else converges to the same evolutionary sequence too soon:

So the 2bo$2ob2o$2bo! ancestor of the TL is in the wrong orientation and gets mixed up with the completed pentadecathla.

The two-glider interchange and all of the above three-glider variants also fail to work for an additional reason. The two gliders would interfere with the pentadecathlon-making gliders. The following shows this and also the pre-TL wrong-orientation problem:

Code: Select all

x = 28, y = 16, rule = B3/S23
24bo$23bo$23b3o3$21b2o$2o18bobo$b2o19bo4bo$o4bo5b2o2b2o8b2o$5bobo2bobo
2bobo8b2o$5b2o5bo2bo3$2b3o$4bo$3bo!

... So ten gliders is minimal as far as I'm concerned, anyway!

And calcyman's prediction comes true! (I can't find the Catagolue page he posted it on, sadly.)
EDIT: I love how the synthesis of the figure eight is catalysed by the pentadecathlon.

I have a feeling you might be thinking of codeholic's old post in this thread:

I bet it's going to be figure 8 on pentadecathlon, i. e. period 120.

Funnily enough, he also correctly predicted that p24 would be the next to show up:

If you're talking about asymmetric soups, then I would bet it's going to be period 24, namely a figure eight on pulsar.

Oops! This was very odd. I usually check my "view your posts" page, and open all changed pages on their last pages, but somehow, today, I opened all of them on their first pages. I had noticed the error on all the other topics, but not this one.

Also, this points out that my attribution notation for this synthesis was incorrect (and as a result, almost two dozen other related syntheses as well). Thanks for the correction!

Can't find the discoverer — Catagolue's /attribute doesn't seem to be working for higher symmetries at the moment.

[77topaz]

It's most likely that /attribute can't find the discoverer because the haul in which it was discovered has already been auto-deleted - this is quite possible, as carybe was (up until a few hours ago) submitting hauls fast enough they get auto-deleted in less than 12 hours. This also means it is extremely likely the discoverer was carybe.
