For instance, tree/forest posets have a very simple structure and have a known hook-length style formula enumerating their linear extensions, but I wasn't able to ... Websimilar to that of NCB(n), we de ne a poset NCD(n) which we suggest as the type Danalogue of NCA(n) and prove the following theorem. Theorem 1.1. The poset NCDn is isomorphic to NCD(n). In particular, this gives a di erent proof that the poset NCDn is indeed a lattice [12, Theorem 4.14]; see Proposition 3.1. We should mention that,
