# Difference between revisions of "User:Saka/OCA Spaceship searches"

This is a page to keep track of some spaceship searches I do in OCA rules to make sure I don't repeat them.
Notation for the "Partial" result:
[Partial length (full, as provided by search program)] - [# of columns that change after <period> gens]
