“…According to h av exact and to h av (LPOMext), we found the following equivalence classes of chlorophenols: [2,3], [5,7], [6,9], [8,10], [11,14], [12,13], [15,16], [17,18]; and according to h av (LPOM0), these ones: [2,3], [5,7,8,10], [6,9], [11,14,15,16], [12,13], [17,18]. The fusion of [5,7] and [8,10] as well as that of [11,14] and [15,16] in LPOM0 arises from the additional symmetries because the incomparable objects are considered as isolated.…”
