Phone Keys (Posted on 2021-11-11) Difficulty: 3 of 5
There are 8 keys on a standard telephone that have letters associated with them. Consider Q included with P, R and S; and Z with W, X and Y.

  1   2   3 
     ABC DEF
     
  4   5   6 
 GHI JKL MNO
 
  7   8   9 
 PQRS TUV WXYZ
  
    *   0   #   

How many 8-letter words can you find that use each of these 8 keys exactly once? Using the concept, the 3-letter word KEY would be represented by 539.

Some Thoughts re: soln Comment 2 of 2 |
(In reply to soln by Steven Lord)

In my own compiled word list, I found the same 47 words plus the following 2 additional words:

MUZAKIER
SODALITY

Suprisingly that it was missed by Steve, SODALITY is noted by wordhelp.com to exist in most, if not all, Scrabble word lists to include both SOWPODS and TWL06.
MUZAKIER is noted as absent in most Scrabble Lists, but was added to the recent international Scrabble wordlist CSW19.
There is a likelihood that more English-language words exist that would comply with the problem requirements yet had not found their way into the Scrabble(R) word lists.
