The rotations of coincidence [n+\bar{j}m\to n+jm] are defined by [\delta = \arctan{m\sqrt{3} /(2n-m)}] [n,m\in{\bb Z}], [n\,\gt\,2m\,\gt\,0] plotted for one unique twist rotation as a function of [\Sigma = n^{2}+m^{2}-nm] for [\Sigma\,\lt\,8000], on a logarithmic scale. As in the general case, well defined asymptotic branches are observed which correspond to the terms of the consecutive Farey sequences: the asymptotic branches of the [F_{\rm h}(6)] sequence are drawn in cyan and red.
