โฆ Synopsis
A recent result of Bryant and Lindner shows that the quasigroups arising from 2-perfect m-cycle systems form a variety only when m = 3, 5 and 7. Here we investigate the situation in the case where the distance two cycles are required to be in the original system.

For m = 6 and for all odd composite integers m, as well as for all even integers m > 10 that satisfy certain conditions, 2-poffect m-cycle systems are constructed whose quasigroups have a homomorphism onto qnasigroups which do not correspond to a 2-perfect m-cycle systems. Thus it is shown that for
In this article we give a complete solution to the problem of equationally defining m-perfect (2m + 1)-cycle systems and of equationally defining rn-perfect directed (2m + 1)-cycle systems.
