Is there much in the way of information about when the various common-ish oscillators in this rule were found, and who found them? I know there's that 'stamp collection' of oscillators found by Alan Hensel and Dean Hickerson before 1999, but I have no idea if that was all the known higher-period oscillators known then or just a sample of them.
Objects like xp3_550i826 and xp10_hrrrh seem like they ought to have been found alongside the other objects there.

EDIT: Are there any widely accepted names for any of the small still lifes/oscillators in this rule?

I'm pretty sure only stuff that also works in normal life the domino, and the 2X2 crawler
