Brad, you can download a pre-compiled version of Sage for UBUNTU and I think it will work without problem. Raniere On Sat, Oct 13, 2012 at 6:22 PM, Brad Owens wrote: > > Greetings Experts: > > I have recently become a Linux user, I > have attempted to install Sa

It is a hardware in a way: you use a downloaded Sage on a system with slightly different characteristics. It's a "bug" in Sage in a way - the binary you download assumes a bit too much from the box. Build Sage from source... On Saturday, 13 October 2012 14:03:00 UTC+8, Georgi Guninski wrote: >

Hello !! Well, it is a bug indeed but it looks like it always happen when you look for subgraphs of G isomorphic to the empty graph (one vertex, no edge). So I would say that using this function can be easily avoided in that case :-P Considering that you code does not use t
