The use of latin squares in constructions of nets, affine planes, projective planes, and transversal designs also motivates this inquiry.??.The text begins by introducing fundamental conc

Extensions of Orthomorphism Graphs of Orth(GF(.).) by GF(3).. We will consider the special case of extensions of the orthomorphism graph of GF(.). consisting of linear orthomorphisms of GF(.).. We will extend these methods to the study of extensions of cyclic groups by GF(3)..

(,) for Some Classes of Nonabelian Groups=?GL(2, .) or SL(2, .), . even, .≠2. To establish this bound, we will use partitions of the element sets of the groups. For higher dimensions we will establish lower bounds for .(GL(., .)), . even, .≠2, using even-odd decompositions and partitions of the sets of odd-order elements of the groups.

Elementary Abelian Groups. Itudied using multiplication. The simplest such class is the class of linear orthomorphisms: these are of the form .?.. It is clear that such a mapping is an orthomorphism if and only if .≠0, 1. In this chapter we will also study quadratic orthomorphisms: these map . to . if . is a square and to . if . is a nonsquare.

Projective Planes from Complete Sets of Orthomorphismsrojective planes. In particular we will prove the nonexistence of certain generalized Hadamard matrices, from which the nonexistence of complete sets of orthomorphisms of certain groups can be derived. We will also study Cartesian projective planes of prime order.

Management for Water Quality on Rangelands Through Best Management Practices: The Idaho Approach Act, have impelled states to address nonpoint control, chiefly through best management practices (BMPs) to reach water quality goals. Rangeland BMPs are based on study and experience gained from observing the effects of grazing management and range improvements on the hydrological processes of wate
