Jim Caprioli at The Finland Station

Not when there is an unsolved problem on my mind. I couldn't resist going back to my problem after more conversation in PlanetMath. Finding a set of 16 matrices isomorphic to Z4x|Z4 must be solved first. Continuing my math study and not solving this problem are incompatible actions. All problems on my way must be dealt with effectively. The good news is that I am getting closer. It is likely that the set which I am searching for is a DIrect Sum or Tensor Product of two irreducible representations. Since I know all irreducible representations that option should be simple. But is it?
