Hi, guys. I am not sure that whether there has some else came across the same problem with me. I wanted to compute some formula in the algebra of linear group GL(2,F_q) for some prime power q. Then I asked sage to print the result for me, the format was quite weird. Each row of the 2X2 matrix got printed in two lines. It was something like: 2*[1 0] [0 1] + [1 0] [1 1] + [ 1 0] [g^2 + 1 1] + [ 1 0] [g^2 g] + [ 1 0] [g^2 + 1 g] + [ 1 0] [ 0 g^2] + [ 1 0] [g^2 g^2] + [ 1 0] [ 1 g^2 + 1] + [ 1 0] [ g g^2 + 1] + [g 0] [g 1] + [ g 0] [ 1 g + 1] I think the results can be printed in a more perfect way.
