A simultaneous representation of a group and a bounded poset with lattice automorphisms and principal congruences
Gábor Czédli · arXiv (Cornell University) · 2015
Given a poset $P$ with at least two elements and a group $G$, there exists a selfdual lattice of length 16 such that the collection of its principal congruences is order isomorphic to $P$ while its automorphism group to $G$.
