However, the first one has a smaller bounding box (120 vs. 130).

Thanks for the correction. At the time of the posting, I was going off of the LifeWiki SKOP page, which had SKOP 117 listed as, I believe, thumb 1 on p39 pi-heptomino hassler.

I have spent countless hours trying to find something with the p59 pi hassler; nothing works except fire-spitting, which is one cell too big.

If you're not sure if an oscillator is a SKOP then you can check here

Yes, but SKOP 390 redirects to buckaroo while there is no link for checking SKOP 555. So how do I tell? However, a buckaroo loop probably needs at least 97 cells.

How can I tell if a particular period's SKOP is a Pentadecathlon-based glider shuttle?

Its period would need to be a multiple of 15, but I don't know of any other criteria that it would need to follow.

Thought so too. So why is 60P465 SKOP 465 while 70P555 probably not SKOP 555? In theory SKOP of a multiple of 15 would need only 29 cells, but in practice it is not true. (Thats why I bother asking if these are SKOP)
