On Multiplication Groups of Quasigroups

open access: yesEuropean Journal of Combinatorics, 1984
The author shows that all finite dihedral, symmetric, alternating, general linear and projective general linear groups and the Mathieu- groups \(M_{11}\) and \(M_{23}\) have the following property: they are isomorphic to multiplication groups of quasigroups.

Parastrophes of quasigroups

open access: yes, 2015
Parastrophes (conjugates) of a quasigroup can be divided into separate classes containing isotopic parastrophes. We prove that the number of such classes is always 1, 2, 3 or 6. Next we characterize quasigroups having a fixed number of such classes.

Certain congruences on quasigroups [PDF]

open access: yesProceedings of the American Mathematical Society, 1952
1. Using the ideas of [1],1 we define a lattice-isomorphism between the reversible congruences on a quasigroup and certain congruences on its group of translations. This may be used to get certain properties of the quasigroup congruences from those of the translation-group congruences; for example, it gives a new proof that reversible congruences on a ...

On the Constant-Depth Circuit Complexity of Generating Quasigroups [PDF]

open access: yesTheoretiCS
We investigate the constant-depth circuit complexity of the Isomorphism Problem, Minimum Generating Set Problem (MGS), and Sub(quasi)group Membership Problem (Membership) for groups and quasigroups (=Latin squares), given as input in terms of their ...

Quasigroups, right quasigroups, coverings and representations

open access: yes, 2018
For a fixed quasigroup Q, equivalences are established between the following categories: (i) the category of modules over the quasigroup; (ii) the category of representations of a stabilizer in the universal multiplication group; (iii) the category of representations of the fundamental groupoid of the Cayley diagram of the quasigroup in the category of

On Birkhoff's quasigroup axioms

open access: yesJournal of Algebra, 2016
Quasigroups form a variety only if two additional operations, namely \(/\) and \(\backslash\) are considered. Birkhoff formulated six identities that define equationally the variety of quasigroups. Evans proved that only the most natural four identities are needed.

Investigation of Some Cryptographic Properties of the 8x8 S-boxes Created by Quasigroups [PDF]

open access: yesComputer Science Journal of Moldova, 2020
We investigate several cryptographic properties in 8-bit S-boxes obtained by quasigroups of order 4 and 16 with several different algebraic constructions.
