GAP: Sesquilinear and quadratic forms

This package can be used for work with sesquilinear and quadratic forms on finite vector spaces; objects that are used to describe polar spaces and classical groups. It provides: * A way to create and use sesquilinear and quadratic forms on finite vector spaces. * An operation which finds an isometry between two forms of the same type. * An operation which returns the forms left invariant by a matrix group.
