Change log for Magma V2.10-16 (Released 23/9/2003)

Algebras

·An error which caused the Lie algebra function HighestWeightRepresentation to sometimes return incorrect answers has been fixed.

Geometry

·A bug coercing from a projective scheme into an affine ambient (and vice versa) has been fixed.

Groups

·A bug in distinguishing between SymmetricGroup(n) of types GrpPerm and GrpPermCox has been fixed.

Rings and Fields

·The inverse of the map returned by IsIsomorphic for absolute fields defined by non-monic polynomials was wrong. This has been fixed.

·A failure that sometimes occurred in the residue class field map for prime ideals in non-maximal orders has been fixed.

·An internal error caused when the div operator was used with orders of quadratic fields has been fixed.

·An error when forming the residue class field of an algebraic function field whose constant field is an algebraic function field of infinite degree has been fixed.

·Some minor memory problems in the p-adics have been fixed.

·A bug in BasisMatrix of non-simple equation orders of number fields has been fixed.

·A bug in Index of a infinite order of an algebraic function field has been fixed.
