It occurs to me that any word which is valid in Boggle must consist of an
uninterrupted run of letters which are *right next to each other* on the board.
Hence, any digraph which *doesn't* consist of a pair of neighboring letters,
*cannot* occur in any valid word.

Interesting idea. There are 25 letters on each board, some are always repeats. I think I'd need
a good regex so I wouldn't have to run the filter command multiple times. How's your regex?
On the other hand, I suppose filtering out even just 2 or 3 letters might make a dent. I'll try
