Fill the plane with the square spiral with cells numbered as in A275609; sequence gives the cells along the South spoke starting at the origin.
The Example section of A275609 shows the central portion of the spiral very clearly. The link below shows a larger portion but is harder to read.
N. J. A. Sloane, <a href="/A275609/a275609.txt">Central portion of spiral, shown without spaces</a> [The central 0 (at (0,0)) has been changed to an X. The illustration shows cells (x,y) with -35 <= x <= 35, -33 <= y <= 36.] The present sequence gives the numbers to the South of the X.
