Rickye, the playfair keyword won't have any letters recurring (and none omitted).
Orson, 41's answer is WYCH, so it's likely that the last row of the playfair square is *WXYZ or **WYZ. Then the first two cells of the 41 entry would be YZ. If you consider the same happening for all the entries which extend into the playfair square, then I suppose the square itself is encoded...
I've done enough cold-solving to give quite a few intersections. Eg 13 SPADER and 14 ACETIC. Which gives the results of encoding AD and AC sharing the same first letter, perhaps suggesting that these letters are all aligned on a rank or file of the playfair square, eg. DA*C
or CA*D. Which suggested 'Boxing Card' - but that doesn't work out.
Various guesses are worth entertaining, the middle cell of the second rank up being Q, and K being in one of the barred off cells of the central rank, etc.
I've a few things on, but hope to look at this again in the evenings next week...
