[sage-support] Small groups library is missing

Dear Sage supporters, I just did an install of Sage-3.3 from sources. I also installed the optional packages database_gap-4.4.10 and gap_packages-4.4.10_6. Nevertheless, when doing sage: gap('NumberSmallGroups(128)') an error is raised, telling that the Small Groups library is required but not

Hi Dave: I'm also just learning the basics of interacting with Singular through Sage. So probably someone else on the list can answer your question better than me. Still, i'll take a stab at it. Carrying on with your/Singular's notation, try sage: singular.setring(AC) sage: sol= singular('SOL

I'm sorry for not being accurate enough to use the correct term for what I'm talking about. Luckily, you're smart enough to understand my needs, so it seems that I should really go for this new symbolic package, so that we can get something better for symbolic integrals and laplace/inverse laplac

To the best of my knowledge, the new symbolic (are you referring to pynac?) should just be considered as the core of symbolic, and the utilities functions should be continue to exist on top of SAGE (or any other package actually used, like maxima). Unfortunately, it seems that the inverse laplace

Well, that was exactly what I was going to do, but I have no idea how to implement something like a (symbolic) k-th order derivative, such that I could then do the limit. Moreover, the derivative seems to be something close to the core of something like a CAS, so I don't think I could be able to h
