RS-permutation

R5-Permutation An R5-permutation Q corresponds to a reflection, where the chirality or achirality of each prohgand (in isolation) is not changed. For example, an RS -permutation on the two prohgands p s of 1 generates 1 itself. On the other hand, an RS -permutation on the prohgands p and p of 2 generates 3.
