 Letter Cubes 5 (Posted on 2006-06-28)
In this game of Letter Cubes, each word of one to four letters in uppercase below are used. Except for the letters "Q" and "X", a different letter of the alphabet is on each face of each of the four cubes.

Can you identify the six letters on each cube?

FOR EACH WORD A CUBE IS USED JUST ONCE:
FORM, GAZE, HACK, HOLE, LAZY, LIMP, SING AND VENT

The below program is able to solve the puzzle even with the information from HACK, VENT and AND missing (by overlaying with one of the other words, which provides no more information than that word appearing only once). It just goes faster if HACK, LAZY and AND are in fact used.  There are probably alternate sets of words that could have been left out and still had a solvable puzzle.

The program:

REM  FOR, EACH, WORD, A, CUBE, IS, USED, JUST, ONCE

finds a letter grid of letter pairs found within the same words (not necessarily adjacent):

(see C vs K, for example, or A vs N)

but either way, the solution is found as:

ABOPSV|CDFGLT|EIJKRY|HMNUWZ|

as being the four cubes.
