## Abstract We establish natural bijections between three different classes of combinatorial objects; namely certain families of locally 2โarc transitive graphs, partial linear spaces, and homogeneous factorizations of arcโtransitive graphs. Moreover, the bijections intertwine the actions of the re

Abstract
We study arcโtransitive homogeneous factorizations of a complete graph on 81 vertices and give an almost complete description of all possible factors that arise. In particular, we show that there exists an arcโtransitive homogeneous factorization of K~81~ such that the factors are isomorphic to the Hamming graph H(9,2). This gives rise to an edge partition of K~81~ into 90 copies of K~9~ and it turns out that these copies of K~9~ form the blocks of the exceptional nearfield affine plane of order 9. ยฉ 2005 Wiley Periodicals, Inc.

For any odd prime power q, all (q 2 &q+1)th roots of unity clearly lie in the extension field F q 6 of the Galois field F q of q elements. It is easily shown that none of these roots of unity have trace &2, and the only such roots of trace &3 must be primitive cube roots of unity which do not belong
The flag-transitive affine planes of order 125 are completely classified. There are five such planes.
