I don't remember seeing that.

bottom of the matrix.
Huh, that is weird, because I definitely didn't have that experience.
Attached is a screenshot of what I get. The top row is all the powers of
1 mod 7 (which are all 1), and the left row is all the 0th powers of a mod
7 (which are all 1). The right row is Fermat's Little Theorem, that the
6th powers are also 1 mod 7. The matrix itself is
{{{
sage: p=7
sage: matrix(p-1,[mod(a,p)^b for a in range(1,p) for b in srange(p)])
[1 1 1 1 1 1 1]
[1 2 4 1 2 4 1]
[1 3 2 6 4 5 1]
[1 4 2 1 4 2 1]
[1 5 4 6 2 3 1]
[1 6 1 6 1 6 1]
}}}
I feel like I must be missing something.
