G.f. A(x) satisfies A(x) = 1 + x*(A(x)³ - A(x)⁴ + A(x)⁵). A271469

a(n) = s(1)t(n) + s(2)t(n-1) + ... + s(k)t(n+1-k), where k = [ (n+1)/2 ], s = (Fibonacci numbers), t = (composite numbers). A24461

a(n) is the numerator of the probability that the procedure described in A372422 successfully ends with the selection of a single person, starting with n persons. A372482
