Four-generated quasiorder lattices and their atoms in a four-generated sublattice
Quasiorders, also known as preorders, on a set A form a lattice Quo(A). We prove that if A is a finite set consisting of 2, 3, 5, 7, 9, or more than 10 elements, then Quo(A) is four-generated but not three-generated. Also, if A is countably infinite, then a four-generated sublattice contains all ato...
