The OEIS Foundation is supported by donations from users of the OEIS and by a grant from the Simons Foundation.

Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

 OFFSET 1,2 COMMENTS The positions reflect square radii which are uniquely twice a square integer, that is, the inclusion of only one square on the y = x line. LINKS FORMULA a(n+1) = A235142(n) + 1 , a(1)=1. EXAMPLE for n=3, a(3) = 11.  The eleventh term of A235141 is 1 reflecting an increase in the square radius of the circle from exactly 8 to the open interval of (8,9). CROSSREFS A000548(n) = (A001481(1 + (a(n+1)-1)/2)/2. Cf. A235141, A234300.
