Hi David and all, I read your mail and I'm agree with your first and second proposal, I know that problems are hard to solve but this problems are nicest for me!!!. I think I'll take the to problem on, but I'll start with the automorphisme work, what do you think?, now I'll start with trying the l

Hi Pere, good to hear from you again. 1. Nick Alexander's suggestions (e.g., coding theory over rings) are good ones. 2. Another problem is to write code to compute the automorphism group of a linear code. It is surprisingly hard to write a fast algorithm to do this, even in the case of binary l
