On some finite groupoids with distributive subgroupoid lattices
Konrad Pióro (2002)
Discussiones Mathematicae - General Algebra and Applications
The aim of the paper is to show that if S(G) is distributive, and also G satisfies some additional condition, then the union of any two subgroupoids of G is also a subgroupoid (intuitively, G has to be in some sense a unary algebra).

On symmetries and parallelogram spaces.
Mirko Polonijo (1985)
Stochastica
The notion of a TST-space is introduced and its connection with a parallelogram space is given. The existence of a TST-space is equivalent to the existence of a parallelogram space, which is a new characterization of a parallelogram space. The structure of a TST-space is described in terms of an abelian group.
On ternary semigroups of homomorphisms of ordered sets
Antoni Chronowski (1994)
Archivum Mathematicum
The paper deals with the characterization of ordered sets by means of ternary semigroups of homomorphisms of ordered sets.
