I tried mailing this to the original poster of the question, but I just
got mail telling me it's sitting in a queue someplace, bouncing around.
I am sorry if this response is inappropriate to the comp.graphics
newsgroup, but I think that this is my best chance of getting in contact
with the individual who requested the info.  My response follows:

My name is Ed Semeniuk, and I am a co-op student from the University of
Waterloo.  I am currently on work term at Motorola Canada Ltd., and I
read this in the comp.graphics newsgroup:

No problem!

Myself, I am not an expert on Rubik's Cube.  But I do have a friend who
is a puzzle fanatic, and has close to 100 puzzles (I think).  He has
done much independent group theory research, and even publishes a
newsletter on the subject of puzzles like Rubik's Cube.

As to your original question, he has written a program called Q-Solve,
which he has ported from the Commodore64 to the Amiga and the IBM PC.
The IBM version has been extended to solve cube puzzles of up to
10X10X10.

If you are interested, please respond to me and I will try to put him in
touch with you through my account at Motorola.  Even if you have just a
casual interest in cube-like puzzles and their solutions on computer,
I'm sure that my friend would like to hear from you.

His name is Mark Longridge, and he is currently living in Oshawa,
Ontario, Canada.  If you would like to hazard a phone call, his home
phone number is (416)725-4420.  I'm sure he would have the BYTE
reference you were asking about.

I look forward to hearing from you!

>    Any help would be greatly appreciated.

I hope this helped.
