Part of the problem is how do I send you an APL program that you can look
at? The best I can do is copy out the Vector, pull it into an MSword
document and hook it as an attachment (after testing to make sure it
works/copied correctly).

There's an essay on the J-wiki about this -
http://www.jsoftware.com/jwiki/Essays/N_Queens_Problem - though I think
it may have a mistake: aren't there 96 solutions if one counts all the
rotations and reflections of the basic 12 (not 92 as stated in the essay)?
There's also a Dyalog solution: http://www.dyalog.dk/dfnsdws/n_queens.htm.
I've seen the one-liner but don't recall in which issue of Vector.

familiarity with the symbolism is crucial.
Absolutely (this is our common response to the "cryptic!" accusation).
And I have a one line APL function for printing out all
solutions for n queens on a board.
Send that along. I'd like to give a shot.
