{wiki=Multiplicative_group_of_integers_modulo_n}
The multiplicative group of integers modulo \\( n \\), often denoted as \\( (\\mathbb\{Z\}/n\\mathbb\{Z\})^* \\) or \\( U(n) \\), is the set of integers that are relatively prime to \\( n \\) under the operation of multiplication, with the multiplication performed modulo \\( n \\).
