41CL Quiz: Determinant of 30x30 anti-Identity matrix

Disclaimer: please take this with the humour it's meant to be. I mean no meanness.

Just to rub salt in the wounds of all the HP owners (except perhaps for the Prime users), my 9750gII took 22 seconds to calculate the determinant of the anti-identity matrix. Mind you, it took me nearly twelve minutes to input the silly thing because I can't automatically generate an anti-identity matrix. But I thought that was pretty good calculation speed.

Now back to the subject at hand... It's interesting to see the little secrets hidden away in the bowels of HP's ROM files, especially ones that had their foundations way back in the late seventies. I wonder where—and when—the functions from my calculator originated from?
