I was wondering if, in Predrag's book, he meant to use n!
(as in n = defining dimension) in equation 6.28? If not,
what is N?
Tony Kennedy:
It does look as though N ought to be n. I am copying this to
Predrag so he can make a correction if necessary (now that it
is too late to stop the presses!).
(Tony to Predrag: Sam is trying to show by birdtracks that
the square of a Pfaffian is a determinant).
