Average size of the principal filters of the atoms of atomistic lattices
Let $L_n$ be a boolean lattice with $n = 2^m$ elements, $m \ge 2$.
Remove arbitrarily a meet-irreducible element, excluding the atoms and the greatest element, to get lattice $L_{n-1}$. Continue till remaining with just the least and greatest elements and the atoms.... -
