I initially didn't think that its necessary to talk about the source of the
lists "rep" and "Edge" and hence I didn't include those in the question.
I thought the question could be answered in the abstract.
But then for me it gives me this "error" message quoted in the first post
for q=2, n=3

Is it only because I'm old that I see something inelegant about a post
that re-quotes (without commenting on any but the newest) eight
generations of quoted matter, including ninety blank lines and four
copies of "You received this message because"?

The time trouble starts at the point in the code where it doesn't matter
where the permutation matrices comes from.
What the main part does is basically this.
Given any set of matrices of dimensional k it produces by the "product" and
"zip" command all possible ways of distributing those mat

This is how "Edge" is created,
g = graphs.CompleteBipartiteGraph(n, n)
Edge = []
for (a,b,c) in g.edges ():
Edge.append ( (a,b) )
This is how "rep" is created,
Fq2 = []
for i in range (q):
for j in range (q):
Fq2.append (matrix([[i],[j]]))
SL2Fq = []
for i1 in range (q):

Perhaps you can post rep and Edge in that case (in a format that can
be copy+pasted), or put them into a file and attach it or upload it
somewhere.

I missed that. Is it possible that the error is entirely due to the
way sagecell writes it to a file for execu
The poster has not provided an example producing the error.
One needs to increase q and/or n, as it is mentioned in the post.

no, not at all. It's very typical that the human-readable output (e.g.
think of formulae with indices, inegrals, etc)

This is really weird that SAGE output that I copy pasted here can't be
copy-pasted back into SAGE as an input!
So here it is again written differently!
rep = [ matrix ([[1, 0, 0, 0], [0, 0, 0, 1], [0, 1, 0, 0], [0, 0, 1, 0]] ),
matrix ([[1, 0, 0, 0], [0, 0, 0, 1], [0, 0, 1, 0], [0, 1, 0, 0]] )

For the q=2 , n =2 (the smallest test case) we have,
Edge = [(0, 2), (0, 3), (1, 2), (1, 3)]
rep =
[
[1 0 0 0] [1 0 0 0] [1 0 0 0] [1 0 0 0] [1 0 0 0] [1 0 0 0]
[0 0 1 0] [0 0 1 0] [0 1 0 0] [0 1 0 0] [0 0 0 1] [0 0 0 1]

I am not sure how to include "rep".
Its a list generated by a set of operations somewhere else.
I am generating "Edge" by extracting the edges of the graph K_{n,n}

So I have this SAGE code which takes in two integers q and n and it
generates ~ (q^3)^(n^2) 0/1 matrices and does a sum of their characteristic
polynomials.
I got answers for (q = 3, n = 2), (q =2 , n = 3) and (q=2, n=2)
For any higher number the code runs for ~1hr and then it says,
