I have made some lists named K[i], i= 1 to 48, with matrices, but this doesn't make maple happy, and I get 'Error, invalid subscript selector'. The problem is obvious that K[i] is taking element i in the list K, and I get problems when I want to take list K[i] and look at element j. So, how do you give lists names with indices?

hi. I am trying to make a list of 2 by 2 matrices with entries from Zp. (for the moment p=3) I managed to make the matrices, but I can't for the life of me get them over in a list. This is the code I have written, and I would love some help, or an alternative solution. E := Matrix([[k, i], [j, l]]); for k from 0 to p-1 do for i from 0 to p-1 do for j from 0 to p-1 do for l from 0 to p-1 do E; print(E); end do ; end do ; end do ; end do;
