We study the minor relation for algebra homomorphims in finitely generated quasivarieties that admit a logarithmic natural duality. We characterize the minor homomorphism posets of finite algebras in terms of disjoint unions of dual partition lattices and investigate reconstruction problems for homomorphisms.

An abstract characterization of such “minor posets” in terms of colorings of partition lattices is given, and infinite families of examples as well as some constructions that can be used to build new minor posets are presented.

Topology swapping is validates as a uniform way to create new dual adjunctions and dual equivalences and it is proved that, for every finite algebra of finite type, each dualising alter ego gives rise to a partner duality.

It is observed that among Steiner systems, those which yield join-irreducible members of $\tilde{\Omega}$ are the − 2-monomorphic SteinerSystems, the simple minor quasi-order.

We investigate essential variables of dual operations (or co-operations) in a rather general category-theoretic setting. During this investigation, we collect some results about the essential arities
