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.

Darn! I was expecting something much more interesting. Maybe I'll make it an irregular heptagon. Nonetheless, thank you for answering my question! :)
