pydmqmc.utils.generate_ijab_symmetries_array

pydmqmc.utils.generate_ijab_symmetries_array(i, j, a, b, eight_fold=True, rhf=True)

Generate an array of valid symmetry permutations of the orbital indicies.

Assume physics notation.

Parameters:

i, j, a, b

Orbital indexes.

eight_fold

Whether or not the system is 8-fold spatially symmetric.

rhf

Use restricted Hartree–Fock; indicates spin symmetry.

Returns:

array

All valid i, j, a, b permutations
