Dear pari-users,

In qfisom, I am guessing that the isomorphism is supposed to be definedover Z, i.e. the transformation matrix is unimodular. This is not soclear from reading ??qfisom.

Is there any way to do this computation over Q, i.e. allowing thetransformation matrix to be any non-singular rational matrix?


Cheers,
Jeroen.
