A307446 -id:A307446 - cp's OEIS frontend

A307447 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.
