Smallest Known Oscillators to p106 (and Beyond)

[Kazyan]

All of those look optimal from passing attempts at improvements, except for p248. There exists a non-obvious figure 8 placement, which saves 3 cells from the SKOP:

Anyone have an RLE for 143 (rattlesnake on 66p13)?

Anyone have an RLE for 143 (rattlesnake on 66p13)?

I only know how to construct a form with 100 cells, but the wiki claims 99 (I assume this is why you're asking).

In this form, the rattlesnake's snake needs to be replaced by an eater.

This could drop to 66 cells if there's a mold timing where both oscillators are in their minimum population at the same time, but I didn't find one.

For 74 = 37*2 it would be hard to beat Raucci's p74. For 555 = 37*15 there is already a glider shuttle that's smaller than the p37. For multiples of 16+ the block deletion trick doesn't work.

Edit: removed p444 = 37*12 as there is a smaller glider loop oscillator.

It can't improve the periodic glider loops because of the fallback (as noted in Discord).
