[sage-support] problem installing spkg lie-2.2.2.p5

'sudo ./sage -i lie' gives me an error message (copied below). I'd appreciate advice. Sage 6.4.1 Mac OS X 10.6.8 daniel@df$ bison --version bison (GNU Bison) 2.3 I notice the installer says Host system: Darwin df 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun 7 16:33:36 PDT 2011; root:xnu-1504

[sage-support] Re: number of rational points of Fermat curves over a finite field

With http://trac.sagemath.org/ticket/16953 (hint: needs review) you can do: sage: F. = GF(13^2) sage: P2. = toric_varieties.P2(base_ring=F) sage: C = P2.subscheme(x^8 + y^8 + z^8) sage: C.cardinality() 512 Thats of course a generic count, you could be much smarter just for Fermat curves. Though

[sage-support] number of rational points of Fermat curves over a finite field

Hi Sage-support: At his request, the question below is posted for Norm Hurt, who is not on this list. - David I was reading a recent paper of Arakelian and Borges on Frobenius nonclassicality of Fermat curves with respect to cubics, in which at some point they state that the curve C: X^8 + Y^8 +

[sage-support] is_valid returns True for invalid matroid

from sage.matroids.advanced import setprint M=Matroid(groundset='abcdef',circuit_closures={1: ['ab'],4: ['abcde'],6: [ 'abcdef']}) setprint(M.circuits()) setprint(M.circuit_closures()) M M.is_valid() The set 'ab' is a circuit closure with rank 1, therefore it must be a parallel pair. This is conf
