Abstract

Considering a special double-cover $Q$ of the symmetric group of degree 3, we show that a proper non-regular approximate symmetry occurs from its quasigroup homogeneous space. The weak compatibility of any two elements of $Q$ is completely characterized in any such quasigroup homogeneous space of degree 4.

Keywords: quasigroup, Latin square, action matrix, quasigroup action, homogeneous space, approximate symmetry, intercalate, compatibility
