Groups of automorphisms of tournaments (Q5959741)

The main topic of the paper is to describe the class of weakly associative lattice groups (wal-groups) isomorphic to wal-groups of automorphisms of tournaments. The author shows that the class of wal-groups that can be interpreted as subalgebras of the class of all wal-groups of automorphisms of tournaments is a proper subclass of the class of all wal-groups. He characterizes this class of wal-groups and describes some of its properties.
