Krishna Murthy and Gopala Kishnamurthy [7] showed that real non-total symmetric one-dimensional alternating representations of a crystallographic point group not only induce the magnetic variants associated with the point group but also gives the number of constants required to describe any physical property for the induced magnetic variants.
Because they could be considered as small incommensurate distortions of periodic structures with a crystallographic point group, they could be fit into the schemes of crystallography.
