Wilson's theorem - Wikipedia
https://en.wikipedia.org/wiki/Wilson's_theoremGauss proved that where p represents an odd prime and a positive integer. The values of m for which the product is −1 are precisely the ones where there is a primitive root modulo m. This further generalizes to the fact that in any finite abelian group, either the product of all elements is the identity, or there is precisely one element a of order2 (but not both). In the latter c…

WILSON’S THEOREM: AN ALGEBRAIC APPROACH
alpha.math.uga.edu › ~pete › wilson_easyWILSON’S THEOREM: AN ALGEBRAIC APPROACH PETE L. CLARK Abstract. We discuss three algebraic generalizations of Wilson’s Theorem: to (i) the product of the elements of a nite commutative group, (ii) the product of the elements of the unit group of a nite commutative ring, and (iii) the product of the nonzero elements of a nite commutative ring.
