Dear all, I'm currently working on writing some python that can produce a quadratic form from genus invariants. I've already implemented the rational invariants case, and would be willing to put it into Sage at some point.
For the genus invariants I need to do variable substitutions on quadratic forms. There does not appear to be a function to do this in the quadratic forms class, so I've had to make my own representation. There is an implementation for particularly simple substitutions, but not more complex ones. Is this something that should also be fixed?
