• a(n) = a(1) + a(2) + ... + a(n-1) - a(m) for n >= 3, where m = 2^(p+1) + 2 - n and p is the unique number such that 2^p < n - 1 <= 2^(p+1), starting with a(1) = 1 and a(2) = 2.at n=18A049905
• G.f. satisfies: A(x) = 1 + x*exp( Sum_{n>=1} A226908(n)*A(x^n)*x^n/n ), where A(x) = exp( Sum_{n>=1} A226908(n)*x^n/n ).at n=15A226907
• Least prime whose square contributes to A234429.at n=24A247980
