make_point_group

libcasm.sym_info.make_point_group(

xtal_prim: Prim,

factor_group: SymGroup,

) → SymGroup

Construct the prim point group as a SymGroup

Parameters:

• xtal_prim (Prim) – The libcasm.xtal.Prim.

• factor_group (SymGroup) – The factor group of prim, as calculated by make_factor_group().

Returns:

point_group – The prim point group operations, constructed by removing the translation from prim factor group operations. Degenerate symmetry operations are not added. The resulting point_group is its own head group, not a subgroup of the input factor_group.

Return type:

SymGroup
