Hi Pere: There is nothing on completely regular codes in SAGE or even in GUAVA, so this would be great! I downloaded your tarball and tried to read it. A few comments: 1. It needs lots more documentation, explanation, and examples. 2. If you define a (Python) Codeword class, please be careful. At the moment, all codewords are vectors in the ambient vector space. In other words, they get inherited methods from FreeModule. This blurs the mathematical distinction between codewords (elements of a code C) and vectors (elements of the vector space F^n which C is contained in). However, it also makes the users life much simpler, so that it the way it is set up now. This isn't "written in stone" but if you create a new Python Codeword class, it either (a) might not get used since FreeModule seems to have all the methods needed or (b) would have to be integrated into the existing stuff (in coding/linear_codes.py, etc). Just something to think about. Does your code compute coset leaders? If so, can it compute a syndrome table faster than GUAVA's SyndromeTable?
