We investigate and present a NG groups that consisting of consisting of non-bijective transformations cannot be
subset of symmetric groups by using the notion of AntiGroups. In addition, we study some several examples and
basic propertie of these groups. However, in particularly, we find all NG-groups that not subsets of S3 are
AntiGroups of types [4]
