This bug has been in all versions of Magma since V2.5, but happened only rarely. It was found in verification of a permutation representation of Lyons group (degree 8835156). - A bug in creating elements of the character ring of a group with rational but non-integer values has been fixed. - A print level of `"Magma"` for `GrpLieElt` is now recognized. - `HasComputableSubgroups` returned false too often and is now fixed. - A spurious error message that sometimes appeared when computing modular representations of a group has been eliminated. ## Language and System - A bug in the construction of large sequences has been fixed. ## Lattices - A bug in the function `ShortVectors` has been fixed (when the bound was large). ## Linear Algebra - The operators `lt`, `le`, `gt` and ge now work for matrices and vectors. ## Rings and Fields - A bug in `IsConstant` for an algebraic function field element has been fixed. - A bug involving residue fields of algebraic function fields whose constant field is a polynomial fraction ring has been fixed. - Better error checking is being done on `NumberOfPlaces`. It will now give an error message when a combination of the constant field and the degree is too large. - An error finding a place of a given degree of function field has been fixed. - A memory management problem in taking products of quadratic forms has been dealt with. - A bug in `Reduce` of an order of a function field has been fixed. - Several bugs in [`StrongApproximation`](../GlobalFields/ClassFieldTheoryForGlobalFunctionFields/related.md#function-strongapproximation-divfunelt-plcfunelt-fldfunelt) for function fields have been fixed. - A bug fix and speedups in the computation of discrete logs in `RayResidueRings` of global function fields have been achieved. - A bug fix in the computation of defining equations for abelian extensions of global function fields has been fixed. - The ordering of the complex conjugates in non-simple cyclotomic fields has been changed to match the ordering for the simple fields. - A bug in `IsIrreducible` for multivariate polynomials has been fixed.
