Multiplicative Group of Reduced Residues/Examples/Modulo 8

Example of Multiplicative Group of Reduced Residues
Consider the reduced residue system $\Z'_8$ modulo $8$ under modulo multiplication:
 * $\Z'_8 = \set {\eqclass 1 8, \eqclass 3 8, \eqclass 5 8, \eqclass 7 8}$

$\left({\Z'_8, \times_8}\right)$ is the multiplicative group of reduced residues modulo 8.
