SUMMARY
Pin Groups serve as the double cover of the Orthogonal Group, while Spin Groups act as the double cover of the Special Orthogonal Group. Both Pin and Spin Groups are classified as groups, but only one of these double covers contains the identity element, confirming that both cannot be groups simultaneously. The distinction lies in the determinant values, where the subset with determinant equal to -1 does not form a group, while the subset with determinant equal to 1 does.
