G.f. A(x) = exp( ∑_n>=1 (n² - A384819(n))*xⁿ/n ) where A384819(k) < k for k >= 1 such that A(x) is a power series with integral coefficients. A384820

a(n) = (8 - 2·n + 11·n² - 6·n³ + n⁴)/4. A289121

a(n) = number of subsets S of {1,2,...,n} having more than 1 element such that (sum of least two elements of S) < max(S). A357283

Expansion of e.g.f. exp(x * (2 - exp(x))). A367876

a(0) = 1, a(1) = 3; for n > 1, a(n) = 2·a(n-1) + 4·a(n-2). A63782
