comment What is this pattern called?
I love that you posted this! I stumbled across this same pattern years ago but didn't think to ask about it online. (Then again, that might have been before I knew about Math.SE.) So, thanks for doing this! :)

comment How can I prove whether a $9\times 9$ square can be filled with L-shaped pieces in a completely “regular” way?
@coffeemath: Mmm...it's an L-shape that's three times as large. I count 9 L-pieces, thus 27 squares, which can and does form an L-shape where each "square" is composed of 9 smaller squares.

+1 for a simpler way to state my thought process and thus simplify the (false) proof.
