Correct me if I'm wrong:

*
There are :
256! (256 pieces)
x 4^256 (each square piece can be put in 4 different positions)
/ 4 (the final solution can rotate in 4 different orientations, but remains one single) *

*
= 2,875 x 10^660 (!) solutions*

Hi Jean-Michel. My calculation would be like this:Corners: 4!

remaining edge pieces: 56!

interior pieces: 196!

and only the interior 196 can be rotated for: 4^196

Divide by 4 for rotations gives:4! 56! 196! 4^196 / 4 = 2.186011490004601*10^559 possibilities

Yikes!!!!

IBM's Big Blue can operate at little over 1 pitaFLOPS (1x10^15

floating points operations per second). Supposing it could

operate continuously, it would only take about

6.931796962216517*10^536 years to run through all the

calculations. I think I'll go buy a lottery ticket with a

1-in-a-billion chances to win (virtually infinitely more likely to win!).

I wonder how many people purchased the game in hopes

to win $2,000,000.

CHUCK
