 OFFSET 1,1 COMMENTS These are the values from Table 1 p.14 of Sun and Moll. REFERENCES D. Bressoud, Proofs and Confirmations: the story of the Alternating Sign Matrix Conjecture, Cambridge University Press, 1999. LINKS Table of n, a(n) for n=1..8. D. Bressoud and J. Propp, How the Alternating Sign Matrix Conjecture was solved, Notices Amer. Math. Soc., 46:637-646, 1999. Xinyu Sun and Victor H. Moll, The p-adic valuations of sequences counting alternating sign matrices, arXiv:0901.4564 [math.NT], 2009. EXAMPLE a(7) = 8 because "the eight solutions to Nu(T(n)) = 7 are 26, 38, 46, 82, 5462, 10922, 10924 and J_15 - 1 = 21844" where J_k = k-th Jacobsthal number = A001045(k). CROSSREFS Cf.
