A tetrabrex is a plane figure formed by four cells of the hex grid, adjacent or separated by the length of an edge. See Catalogue of Polybrexes.

A polyform oddity is a figure with binary symmetry or greater, formed by an odd number of copies of a polyform. Here are the smallest known oddities of various types for the 45 tetrabrexes.
