Parameters

two_l1: array of integers
two_l2: array of integers
two_l3: array of integers
two_l4: array of integers
two_l5: array of integers
two_l6: array of integers: Since L1, …, L6 should be integers or half integers, two_l1 (which means 2 x L1) should be all integers.
ignore_invalid: boolean: If True, returns 0 even for invalid arguments. Otherwise, raise a ValueError.

Returns
