[sage-devel] Directions for idioms of free objects and free abelian groups

2014-04-18 Thread Travis Scrimshaw
Hey everyone, On http://trac.sagemath.org/ticket/15289 I'm implementing monoids and groups indexed by an arbitrary set of generators and Nicolas and I would like your input on some possible idioms. * Is anyone opposed to removing Free* from the global namespace and instead accessing free obj

Volker, Thanks for the workaround. What gets me is that it works in an older version of sage. On Friday, April 18, 2014 9:17:16 AM UTC-7, Volker Braun wrote: > > The problem is that we don't have an algorithm to find out that the group > is finite (short of generating all elements). So it is

The problem is that we don't have an algorithm to find out that the group is finite (short of generating all elements). So it is placed in the "Groups" category instead of "FiniteGroups", and that doesn't have an iterator. There should be an in-between category of finitely generated groups whic

I am trying to get sage to list the elements of a (finite) finitely generated matrix group. It works in version 5.9 installed on a Mac, but not on 6.1.1 on linux or on the cloud, which leads me to believe somewhere between 5.9 and 6.1.1 the .list() operation for finite matrix groups was compr
