Needless to say, this is probably much more and much sooner than most of us were expecting.
Congratulations on beating 40514M, dvgrn!

Nice! New Record!

Generation 36 has the smallest population (46 cells):

10bobo$6bo2bo6bob2o2bo$7b2o10b2o$16b2o!

So that might be a place to start the process of minimization.

Although maybe it's not worth putting lots of effort into minimization if we're soon going to have a flood of new records.

Congratulations on beating 40514M, dvgrn!

Call me insensitive, but I have an initial name suggestion of Patricia, as it beat out the previous named record holder of Wilma (mentioned here) by a surprisingly large margin. (Well, there's also 40514M, but that's only a designation, so let's conveniently ignore it here.)

(Note: this suggestion is somewhat sarcastic, so feel free to ignore it, but after Sir Robin, who knows anymore? I sure don't.)

Yes, I do like watching tropical cyclones; why do you ask? (No, I don't live in a place that experiences them with any regularity.)

In my 3g collisions there is no synthesis of these 4 blocks. however, there is one fitting collision for a block+ship constellation (in a 8x3) box which might be useful. (nothing for the 4x7 option). This allows us to get 3/4 of the inner ship-block circle for 9g (just the last step):

if we can get the remaining block and ship for less than 9g we have an improvement.

I don't see a way to improve it, unless someone finds a 4g way to get the centre at once.

The discussion of the new p64 (and the p16) is great, but it seems like it should all go in the oscillator discussion thread. None of the discussion has utilized the original soup in any way (except the first post). I know I sound like a broken record, and it wouldn't matter for most people, but when updating the pattern collections it would be nice to have all relevant discussion in one place. It will be hard work scouring this nearly 2000-post thread for the few oscillators that were posted here.

Is this the longest-lived known symmetric methuselah?
Incidentally, an unusual skewed-TL constellation forms from two separate half-TLs sometime around t=15k.
