GUAVA

GUAVA is a GAP package for computing with codes. GUAVA can construct non-linear, linear and cyclic codes; transform one code into another; construct a new code from two other codes; perform decoding and error-correction; and can calculate important data of codes quickly. Limited ability to compute algebraic geometric codes.
