Re: [sage-devel] Re: Matrix groups are not uniquely represented, why?

2018-06-01 Thread Simon Brandhorst
Suggestion: (1) Use unique representation for "ambient" objects ( GL(n,k), O(n,k,e), QQ^n). (2) Do not use unique representation for subobjects. (3) Give the .subobject(self, gens) method a (weak?) cache. (4) Modify == to test equality as subobjects/subsets. -- You received this message because
