## Abstract An orthogonal latin square graph (OLSG) is one in which the vertices are latin squares of the same order and on the same symbols, and two vertices are adjacent if and only if the latin squares are orthogonal. If __G__ is an arbitrary finite graph, we say that __G__ is realizable as an O

Automorphism free latin square graphs
✍ K.T. Phelps 📂 Article 📅 1980 🏛 Elsevier Science 🌐 English ⚖ 837 KB

In this paper, we show that there exists an automorphism free latin square graph of order n for all n a 7 and that the number of such graphs goes to infinity with n. These results are then applied to the construction of automorphism free Steiner triple systems.

## Abstract A __decomposition__ 𝒢={__G__~1~, __G__~2~,…,__G__~__s__~} of a graph G is a partition of the edge set of G into edge‐disjoint subgraphs __G__~1~, __G__~2~,…,__G__~__s__~. If __G__~__i__~≅__H__ for all __i__∈{1, 2, …, __s__}, then 𝒢 is a decomposition of G by H. Two decompositions 𝒢={__G

Embedding a latin square in a pair of or
✍ Peter Jenkins 📂 Article 📅 2006 🏛 John Wiley and Sons 🌐 English ⚖ 123 KB

## Abstract In this paper, it is shown that a latin square of order __n__ with __n__ ≥ 3 and __n__ ≠ 6 can be embedded in a latin square of order __n__^2^ which has an orthogonal mate. A similar result for idempotent latin squares is also presented. © 2005 Wiley Periodicals, Inc. J Combin Designs 1

## Abstract Let __G__ be a graph with vertex set __V__(__G__) and edge set __E__(__G__). Let __k__~1~, __k__~2~,…,__k__~m~ be positive integers. It is proved in this study that every [0,__k__~1~+…+__k__~__m__~−__m__+1]‐graph __G__ has a [0, __k__~i~]~1~^__m__^‐factorization orthogonal to any given
