%N Second coordinate of a contiguous path on the odd numbered points of a square lattice leading to a distance-limited bijection with the even numbered points of a square lattice rotated by Pi/6 around the common point (0,0). A307446 gives the first coordinate.
%C For a description of the construction and visualizations see A307446.
