 OFFSET 1,2 LINKS FORMULA a(n) = A001405(n)/A056059(n)^3 or binomial(n, floor(n/2)) = a(n)*A056059(n)^3. EXAMPLE n=14, binomial(14,8) = 3432 = 2*2*2*3*11*13 so g(3432) = A056059(14) = 2, thus a(14) = 3432/(2*2*2) = 429. CROSSREFS Cf. A001405, A056056-A056060, A056201. Sequence in context: A026034 A178381 A037031 * A001405 A126930 A210736 Adjacent sequences:  A056199 A056200 A056201 * A056203 A056204 A056205 KEYWORD nonn AUTHOR Labos Elemer, Aug 02 2000 STATUS approved
