Abstract
A finite set W Rd
is said to realize the group G if
the isometry group of W is isomorphic to G. The isometry
dimension of a group is the minimum dimension of a real-
ization. It is known that the isometry dimension of G is less
than |G| [1]. We show that the isometry dimension of Zn
2
is n. The orbit number of a group is the minimum number
of orbits in a realization. We show that the groups Zn
