symmetryKey関数
リファレンスの説明と例は英語です。見出しと目次は日本語です。
A board's identity up to turning and mirroring it: the smallest of the codes of
its eight turns and mirrors, with every piece the water does not go through
(it may face any way) set to one facing. Two boards with the same key are the
same puzzle. solution is the board with its pieces facing as an answer has them.
