RE: 41CL Quiz: Determinant of 30x30 anti-Identity matrix
Thanks for the puzzle Ángel. It seems to make sense that the determinate of such a matrix would boil down to a lot of 1*1 - 1+1 (or zero) terms with a few 0 - 1*1 terms (-1). So, -29 is related to the dimension. I think it's something like norm(30), or 435 terms, most of which are zero.

Anyway, I thought about how this would look as a function of the diagonal value from 0 to 2. Interesting:

Outside that range, the numbers get big/small very quickly!
Nice how concise such an analysis turns into Python. I'm thinking of writing a python to RPN compiler. Maybe someone here has already done so?
