 OFFSET 1,2 COMMENTS Note that for odd n, the digits will include n itself. LINKS Table of n, a(n) for n=1..18. FORMULA t(n,m)=Min[2*m - 1, 2*(n - m) + 1]; a(n)=FromDigits[{Table[t[n, m], {m, 1, n}], n}, n]. EXAMPLE Row 4 of A157454 is 1,3,3,1. 1331 in base 4 = 4^3 + 3*4^2 + 3*4 + 1 = 125, so a(4) = 125. MATHEMATICA t[n_, m_] =Min[1 + 2*m, 1 + 2*(n - m)]; Table[FromDigits[{Table[t[n, m], {m, 0, n}], n + 1}, n + 1], {n, 0, 20}] CROSSREFS A139038, A003983 Sequence in context: A318811 A352299 A074572 * A027308 A295371 A156069 Adjacent sequences: A157452 A157453 A157454 * A157456 A157457 A157458 KEYWORD nonn,base AUTHOR Roger L.
