Change log for Magma V2.27-3 (Released 1/8/2022)

Matrices

·A bug when computing random matrices over the finite field GF(2^32) has been fixed. Reported by E. O'Brien.

Number Fields

·A crash in the computation of the absolute field of a number field with very large coefficients has been fixed (arising when calling DescentInformation on certain types of elliptic curves). Reported by M. Voznyy.

Polytopes

·An issue where NumberOfInteriorPoints could be off by one for one-dimensional rational polytopes has been fixed. Reported by G. Hamm and J. Hofscheier, who also provided the fix.

Schemes

·An internal crash in BaseScheme called out of Extend for schemes has been fixed. Reported by T. Keller.

·The parameter SkipSingularityCheck has been added to the function RationalPoints so that the singularities check can be skipped at the beginning so that the function does not fail on singular inputs. Example input reported by D. Zureick-Brown.
