Translation complements of C-planes: (I)

  • M. L. Narayana Rao (a1), K. Kuppuswamy Rao (a2) and G. V. Subba Rao (a1)
Abstract

Narayana Rao, Rodabaugh, Wilke and Zemmer constructed a new class of finite translation planes from exceptional near-fields described by Dickson and Zassenhaus. These planes referred to as C-planes are not coordinatized by the generalized André systems. In this paper we compute the translation complement of the C-plane corresponding to the C-system III–1. It is found that the translation complement is of order 6912 and it divides the set of ideal points into two orbits of lengths 2 and 48.
