Not that this isn't already known, but I do love that the r-pentomino is a p16 oscillator here.

When is someone going to find a knightship for this rule? Period 5 is the least possible period, and I've seen partials in several different periods. I think it's attainable.

These are the best partials I got with afind for various oblique speeds:

Partial result of diagonal c/3 checker-board crawler

Here's a completed c/3 signal - and it's a bubble. Both searches from the front and the back seem to get lost in the search space after finding one of these, so I manually joined them together.
