Usage:
Exterior();

Return:
qring

Purpose:
create the exterior algebra of a basering

Note:
activate this qring with the "setring" command

Theory:
given a basering, this procedure introduces the anticommutative relations x(j)x(i)=-x(i)x(j) for all j>i,
moreover, creates a factor algebra modulo the two-sided ideal, generated by x(i)^2 for all i

Example:
