Appears in sequences

• Coefficients of Legendre polynomials.at n=7A001795
• Numerators in expansion of sqrt(1+x). Absolute values give numerators in expansion of sqrt(1-x).at n=15A002596
• Numerator of n!!/(n+3)!!.at n=27A004732
• Numerator of Maclaurin expansion of (t*sqrt(t^2+1) + arcsinh(t))/2, the arc length of Archimedes' spiral.at n=15A091154
• Numerator of Catalan(n)/2^(2n+1). Also, numerators of (2n-1)!!/(n+1)!. Odd part of the n-th Catalan number.at n=14A098597
• Numerators of rationals (in lowest terms) used in a certain high temperature expansion.at n=14A099398
• Divide n! repeatedly by i! for i from floor(n/2) down through 2; a(n) = remaining quotient.at n=28A111866
• Numerator of moments of Chebyshev U- (or S-) polynomials.at n=28A134828
• Subsequence of A071395. The extra constraint is m is not a term if m*q/p is abundant where prime p|m and q is the least prime larger than p.at n=23A333967
