[sage-support] Issue with interface to Gap in 2.8.12

Hi, Is there a limit on the size of permutations with the Gap interface? I managed to get an error today which seems to be due to Gap putting "(...)" at the end of a line. Here's the error: : Gap produced error output Syntax error: expression expected in /home/carlo/.sage//temp/t40/13158//interf

[sage-support] Graph Isomorphisms with Edge Colorings

Hi, I'm working on a problem for which I have symmetric matrices with arbitrary entries. I'm interpreting these matrices as adjacency matrices where the (i,j) entry gives the color for the i-j edge of a graph, and I need to know if the graphs given by these matrices are isomorphic. My current

On http://sagemath.org/doc/html/ref/module-sage.calculus.calculus.html one can read: sage: var('x, u, v') (x, u, v) sage: f = expand((2*u*v^2-v^2-4*u^3)^2 * (-u)^3 * (x-sin(x))^3) # not tested -- trac #946 This seems to work now: sage: var('x, u, v') sage: f = expand((2*u*v^2-v^2-4*u^3)^2

Dear support team, a basic question whose answer i was neither able to find in the Sage Programming Guide nor in http://modular.math.washington.edu/sage/doc/html/tut/: Suppose i have an extension class Foo and an instance X of Foo. What methods must Foo provide in order to make things work like

[sage-support] Feedback from a first-time installer of Sage on a MAC

This was on an iMAC, OS 10.4.10. I went to Sage Free download MAC OSX INSTRUCTIONS.txt <- but the instructions here (dated 22 Aug 2007) did not work for me. I downloaded the sage gz file to my Desktop, then double-clicked it. This produced an error - it just failed after a while.
