This question is a variant of the question posed by Brian Hopkins.
Let pdist(n)$\operatorname{pdist}(n)$ be the number of partitions of n$n$ into distinct parts. Also, let pdist ( S, n)$\operatorname{pdist}(S, n)$ denote the number of partitions of n$n$ into distinct parts parts, all of which come from the set S$S$. (Here again we take S$S$ to be some some subset of { 1, 2, … , n }$[n]= \{ 1, 2, ... , n \}$. )
Is it true that for every t$t$ from 0$0$ to pdist(n)$\operatorname{pdist}(n)$, we can find a set S$S$ such that
pdist ( S, n) = t$\operatorname{pdist} ( S, n) = t$ ?
