In the 5x5 square grid given above, each of the 5 vowels are repeated precisely 5 times.

Divide the grid into five pieces such that each piece contains precisely 5 distinct vowels A, E, I, O, and U.

Note:The five vowels A, E, I, O, and U may or may not be in this order in each of the five pieces.

Note: the two *E* and the two *A* squares can be swapped. So there are 4 solutions in all.

Awesome picture, Charlie!
