Thanks for the replies. There should be a ticket opened for removing the current instructions to use kash, whether or not they are replaced by something else. John On 9 July 2018 at 23:48, Alexander Konovalov wrote: > Note that the Alnuth package for GAP switched from KANT to PARI/GP, > with t

surprisingly, there are freash trac tickets proposing kash interface improvements: https://trac.sagemath.org/ticket/25488 https://trac.sagemath.org/ticket/25494 https://trac.sagemath.org/ticket/22982 (a meta-ticket where kash is a part of) I think it's unfortunately a wasted effort (as far as ka

I imagine it makes little sense to ask for open-sourcing the kash package (have they sold stuff to somewhere, maybe?), although I might be wrong. On Tuesday, July 10, 2018 at 10:31:52 AM UTC+1, Dima Pasechnik wrote: > > surprisingly, there are freash trac tickets proposing kash interface > impro

In other words, either use BooleanPolynomialRing without specifying GF(2), or use PolynomialRing and specify GF(2). If you set sage: xxz = ['x%d'%(i) for i in range(1, 49)] + ['Z'] you have the choice between the following: sage: V = PolynomialRing(GF(2), 49, xxz) sage: V Multiv

Yes sorry... I probably didn't copy and paste well. r=2/sqrt(n(pi)); c = circle((0, 0), r, color="red", fill=True, alpha=0.2, fontsize=8) That's what I do, r is the special for a perfect quadrature of circle. I don't know RDF but seems to give the same result, thanks. As you said the fontsiz
