Though *solve* and *algsys* don't seem to work very well with modulus:2,
polynomial and matrix operations seem to work fine (as long as division
isn't involved). Have you tried setting modulus:2, ratmx:true, and working
in matrices? Determinant, triangularize, etc. seem to work correctly in
this case, though I haven't really thought a lot about it....
