  * When adding a square to an omino, this is precisely the

  * criterion which tells us that adding the square won't leave a

- * hole in the middle of the omino. (There's no explicit

- * requirement in the statement of our problem that the ominoes be

- * simply connected, but we do know they must be all of equal size

- * and so it's clear that we must avoid leaving holes, since a

- * hole would necessarily be smaller than the maximum omino size.)

+ * hole in the middle of the omino. (If it did, then things get

  * 

  * When removing a square from an omino, the _same_ criterion

  * tells us that removing the square won't disconnect the omino.

+ * (This only works _because_ we've ensured the omino is simply

+ * connected.)
