In a previous message, David Broadhurst refers to:
(a.k.a. Sod's Law: no free lunch from modular factorization).
In an abstract algebra course, students were asked to prove
the integers are isomorphic to the cross product of
integers mod p for all primes > 0.
z2 X z3 X z5 X z7 . . .
is isomorphic to the integers.
Two of the professors teaching this class expressed their belief
that this theorem would never have any applications.
Perhaps it has application to
justify Broadhurst-Carmody metaphysics.
