Direct products of Space Group Irreducible Representations


Direct products
This program calculates the direct products between the irreducible representations of space groups for two given k-vectors.

Input data :
  1. Space group number as given in ITA.
  2. k-vector data :
    • Reciprocal lattice basis type, which may be primitive (as in Cracknell-Davies-Miller-Love tables [1]), or dual to the conventional (ITA).
    • k-vector coordinates relative to chosen basis as any three decimal numbers or fractions.
    • Label of the k-vector (up to three letters).
