Quandles of cyclic type with several fixed points
Abstract
A quandle of cyclic type of order with fixed points is such that each of its permutations splits into cycles of length and one cycle of length . In this article we prove that there is only one such connected quandle, up to isomorphism. This is a quandle of order and fixed points, known in the literature as octahedron quandle. We prove also that, for each , the non-connected versions of these quandles only occur for orders in the range and that, for each , there is only one such quandle of order with fixed points, up to isomorphism. Still in the range , we present sufficient conditions for the existence of such quandles, writing down their permutations; we also show how to obtain new quandles form old ones, leaning on the notion of common fixed point.
