The following pickles saved in the pickle jar warn of deprecation when they are loaded: _class__sage_combinat_words_word_AbstractWord__.sobj _class__sage_combinat_words_word_Word_over_Alphabet__.sobj _class__sage_combinat_words_word_Word_over_OrderedAlphabet__.sobj _class__sage_combinat_words_wor

On the subject of pickling I just found out the hard way that the pickle jar is no longer tested by default, since trac_10712, which was merged in 4.6.2 marks the following test in sage_object.pyx long time that tests the pickle jar. - sage: print "x"; sage.structure.sage_object.unpickle_all() +

[sage-combinat-devel] Should cones preserve the given ray order?

Hello! We have a heated debate on http://trac.sagemath.org/sage_trac/ticket/10140 regarding the following issue. When a user writes Cone(rays=[(1,0), (0,1)]) and the internal framework that eliminates unnecessary generators comes up with a cone generated by (0,1) and (1,0) (i.e. same rays but i

An update for the records: After working with Nicolas on the patch on the universal cyclotomic field last week, it seems to me almost finished: - working with the UCF works - constructing matrices over the UCF works - working with a matrix group over the UCF works, including listing all elements
