COMMENT

It is a triangular level, two state each, state machine: {1,2},{3,4},{5,6} I show all three levels. Projection on an hexagon: bb=aa/. 1->{0.5, 0.8660254037844386}/. 2->{0.5,-0.8660254037844386}/. 3->{1,0} /. 4 ->{0.5,0.8660254037844386}/. 5->{0.5,-0.8660254037844386}/. 6->{1,0}; ListPlot[FoldList[Plus, {0, 0}, bb], PlotJoined -> True, PlotRange -> All, Axes -> False];
