Generalized Catalan Numbers x²*A(x)² -(1-x+x²+x³+x⁴)*A(x) + 1 =0. A23421

G.f.: A(x) = exp( ∑_n>=1 [ Dⁿ x(1+x)/(1-x)³ ]ⁿ/n ), where differential operator D = x·d/dx. A159598

a(n) = a(1) + a(2) + ... + a(n-1) - a(m) for n >= 4, where m = 2·n - 3 - 2^p+1 and p is the unique integer such that 2^p < n - 1 <= 2^p+1, starting with a(1) = 1, a(2) = 2, and a(3) = 3. A49908
