Cool ! And I would like to add for combinatorics infrastructure : - implementations of Gray codes (for much faster generation) - iterator for conjugacy class of the symmetric group (the call to Gap takes hours) And I would like to emphasize that there are Cythonization problems with iterators... > - Categories (Morphisms, functorial constructions, optimization, coercion ?) > > - who is interested ? I am. > - what is the preferred week ? Any time in January or the first week of February. > - any thematic suggestion, Depending on the audience (Thierry Monteil ? Samuel Lelièvre ? Timo Jolivet ?), I would like to start the migration of - flat surfaces (quadratic differentials, topolgoy stuff, origamis, ...) - language and symbolic dynamics - tilings Some of it is ready and documented and only needs review. Nicolas Borie will you be there ? If you do, I would like to hear about the code in Sage (and more generally about algorithms) for generating things up to isomorphism (like graphs, Integer vectors and co.).
