Expansion of e.g.f. exp((sin(x) + sinh(x))/2). A306347

Number of partitions of n in SPM(n): these are the partitions obtained from (n) by iteration of the following transformation: p -> p' if p' is a partition (i.e., decreasing) and p' is obtained from p by removing a unit from the i-th component of p and adding one to the (i+1)-th component, for any i.

a(n) = ∑_k=1..n floor(n²/k). A118014

Start with 1013 and repeatedly reverse the digits and add 2 to get the next term. A120214

G.f. A(x) satisfies A(x/A(x)⁴) = 1 + x; thus A(x) = 1 + series_reversion(x/A(x)⁴). A120974

a(1) = a(2) = 1; a(n) = gcd(a(n-1), a(n-2)) + (a(n-1) + a(n-2))/gcd(a(n-1), a(n-2)). A355898
