libcasm.sym_info#

Crystallographic symmetry

The libcasm.sym_info package includes:

  • Methods to construct the prim factor group and point group

  • The SymGroup class to store group elements, multiplication and inverse index tables, and group-subgroup relationships.

Currently, symmetry representations are not accessed in Python directly through libcasm.sym_info, but can be obtained when necessary through, for example, Prim and make_occevent_symgroup_rep().

The libcasm.sym_info module only has a dependency on libcasm.xtal.
