OP here! People are rightfully pointing out that this can be compressed further.

My challenge to you: Implement a compressed representation along with the get_cell and set_cell methods, without resorting to lookup tables!

Also, check out Alejandra's blog at https://goose.love/!

(And yeah, you need 12 or 13 bits, not 10, if you don't want to eliminate symmetries.)
