 OFFSET 1,2 LINKS Table of n, a(n) for n=1..35. FORMULA a(n) = A317390(n,n). EXAMPLE a(1) = 1: 1. a(2) = 29: 1 + 2 * (1 + 13) = 1 + 7 * (1 + 3) = 29. a(3) = 91: 1 + 2 * (1 + 11 * (1 + 3)) = 1 + 3 * (1 + 29) = 1 + 5 * (1 + 17) = 91. CROSSREFS A diagonal of A317390. Cf. A317385. Sequence in context: A325073 A152294 A201487 * A107940 A039416 A043239 Adjacent sequences: A317534 A317535 A317536 * A317538 A317539 A317540 KEYWORD nonn AUTHOR Alois P.
