Hi ! I have been facing problems to describe cyclic codes over finite extension fields. It is easy to do with GF(p), but I can´t explicit codes over GF(p^m) (noticing all the mathematical background). Anyone could provide me an example? Best, -- You received this message because you are subs

Hi guys. Given two n x n matrices M, N, we know it is a big problem to find the positive integer "i" such that M^i = N (There are other hypothesis involved). In my particular case, I would like to do the same for 3 x 3 matrices M , N over F_{11^2} (finite field with 121 elements). Is it poss
