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.

COMMENTS

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.

LINKS

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.

CROSSREFS

Cf. A275609.

The eight spokes starting at the origin are A307193 - A307200.
