I also agree with the removal, with the issue of ATLAS. Maybe we should switch to openblas (IIRC Clément Pernet said it is more state of the art nowadays) :) On Tuesday, September 30, 2014 9:15:59 AM UTC+2, Jeroen Demeyer wrote: See http://trac.sagemath.org/ticket/17072 -- You received

It is certainly on intel and making strides on arm. It covers a few other archs through inheritance from gotoblas2 but it doesn't support power7, never mind power8. I can discuss those more in details for anyone interested. François On 30/09/2014, at 21:15, Jean-Pierre Flori jpfl...@gmail.com

Hello, Let's for sanity's sake suppose that == among all vertex labels of FinitePosets is an equivalence relation. Let's moreover suppose that hashing respects this equivalence relation. Thanks, Then the problem seems to be that in the unique representation

I think we have a SnapPy (or whatever it is called now) interface, but do we have one for this? (Well, no. But *should* we?) http://regina.sourceforge.net/ It uses Python for scripting... and has been around for quite a while. Just curious. Feel free to open a ticket if you would use this!

Otherwise, maybe it can be fixed on the relabel function level (once again, I don't know how it works). I don't see how. I tried many times, and each time I was sent back to this design problem: the default value of the list of vertices is not properly defined, and good a good

Hi Nathann, Whoo hoo. First of all, you put my wrong e-mail address and I am not reading sage-devel all the time. Second of all, I did not write the poset code. As far as I know, it was written by Peter Jipsen and Franco Saliola. I used the poset code in the new class LinearExtensions in
