Appears in sequences

• Denominators of continued fraction convergents to sqrt(509).at n=10A041973
• At stage 1, start with a unit square. At each successive stage add 4*(n-1) new squares around outside with edge-to-edge contacts. Sequence gives number of squares (regardless of size) at n-th stage.at n=36A056640
• Smallest k such that 36^k mod k = n.at n=35A178197
• Semiprimes whose binary and ternary representations are prime when read in decimal.at n=37A279052
