Define a ternary ring from a plane as given at http://math.uwyo.edu/~moorhous/pub/planes/. The file format is line for each line of the plane (how appropriate) with the points it contains which are the integers 0 to N - 1. We assume the first line is 0, 1, to n. For nondesargian planes it is likely to be the unusual ternary ring, for example it won't be the Hall quasifield in the Hall plane.
