Transversals in Latin squares: a survey

IM Wanless - Surveys in combinatorics, 2011 - books.google.com
A latin square of order n is an n× n array of n symbols in which each symbol occurs exactly
once in each row and column. A transversal of such a square is a set of n entries containing …

[图书][B] Orthogonal Latin squares based on groups

AB Evans - 2018 - Springer
Latin squares and mutually orthogonal sets of Latin squares (MOLS) have an old history
predating Euler's work in the late 1700s. With the emergence of the abstract concept of a …

Cycle structure of autotopisms of quasigroups and Latin squares

DS Stones, P Vojtěchovský… - Journal of Combinatorial …, 2012 - Wiley Online Library
An autotopism of a Latin square is a triple (α, β, γ) of permutations such that the Latin square
is mapped to itself by permuting its rows by α, columns by β, and symbols by γ. Let Atp (n) be …

Permutation polynomials and orthomorphism polynomials of degree six

CJ Shallue, IM Wanless - Finite Fields and Their Applications, 2013 - Elsevier
A classic paper of Dickson gives a complete list of permutation polynomials of degree less
than 6 over arbitrary finite fields, and degree 6 over finite fields of odd characteristic …

Row‐Hamiltonian Latin squares and falconer varieties

J Allsop, IM Wanless - Proceedings of the London …, 2024 - Wiley Online Library
A Latin square is a matrix of symbols such that each symbol occurs exactly once in each row
and column. A Latin square LL is row‐Hamiltonian if the permutation induced by each pair of …

Perfect 1-factorizations

A Rosa - Mathematica Slovaca, 2019 - degruyter.com
Let G be a graph with vertex-set V= V (G) and edge-set E= E (G). A 1-factor of G (also called
perfect matching) is a factor of G of degree 1, that is, a set of pairwise disjoint edges which …

Symmetries that Latin squares inherit from 1‐factorizations

IM Wanless, EC Ihrig - Journal of Combinatorial Designs, 2005 - Wiley Online Library
A 1‐factorization of a graph is a decomposition of the graph into edge disjoint perfect
matchings. There is a well‐known method, which we call the 𝕂‐construction, for building a 1 …

New families of atomic Latin squares and perfect 1-factorisations

D Bryant, B Maenhaut, IM Wanless - Journal of Combinatorial Theory …, 2006 - Elsevier
A perfect 1-factorisation of a graph G is a decomposition of G into edge disjoint 1-factors
such that the union of any two of the factors is a Hamiltonian cycle. Let p⩾ 11 be prime. We …

PERFECT 1-FACTORISATIONS OF

MJ Gill, IM Wanless - Bulletin of the Australian Mathematical Society, 2020 - cambridge.org
We report the results of a computer enumeration that found that there are 3155 perfect 1-
factorisations (P1Fs) of the complete graph,(ii) observe that the new P1Fs produce no atomic …

Parity types, cycle structures and autotopisms of Latin squares

D Kotlar - arXiv preprint arXiv:1203.0223, 2012 - arxiv.org
The parity type of a Latin square is defined in terms of the numbers of even and odd rows
and columns. It is related to an Alon-Tarsi-like conjecture that applies to Latin squares of odd …
