Vol. 118 (1985), No. 2, 411–425
Abstract

An approach to Rota’s question about the lattice of partitions is presented. Calculations, based upon the assumption that the lattice of partitions may be approximated by a Gaussian process, indicate that the ratio of the cardinality of the largest set of incomparable partitions to the largest rank is at least 1∘ -----√---
1 − 3 3∕8 1.69 as n →∞.
