Abstract
In this note we select a class of identities with permutations including three variables in a quasigroup (Q, ·) each of which provides isotopy of this quasigroup to a group and describe a class of identities in a primitive quasigroup (Q, ·, \ , / ) each of which is sufficient for the quasigroup (Q, ·) to be isotopic to a group. From these results it follows that in the identity of V.Belousov [6] characterizing a quasigroup isotopic to a group (to an abelian group) two from five (one of four) variables can be fixed.E-mail:
