Hi all,

This comand:
A = Array[Random[Integer] &, {3, 3}]
generates a 3x3 random matrix its terms between 0 and 1.

I need to make a loop that geerates a finite number of matrices, let's
say 512 and this loop check that non of the matrices is equal to
another one (no repeated matrices)

I can geerate thoses random, matrices with this command:
Do[Print[Array[Random[Integer] &, {3, 3}]], {512}]
but I may have two matrices that are equal and also as far as I know I
cann't use the out put because of the command, Print.
