• Let M(n) be the n X n matrix m(i,j)=min(i,j) for 1<=i,j<=n; then a(n) is the trace of M(n)^(-7).at n=28A114359
• a(1) = a(2) = 1. a(n) = a(n-1) + (largest noncomposite {1 or prime} among the first n-2 terms of the sequence).at n=33A120761
• Minimum value of k such that Sum_{i=k..k+n-1} i = Sum_{i=k..k+n-1} i', where i' is the arithmetic derivative of i.at n=5A227390
• a(0) = 0, a(1) = 1, and b = a(n-2) + a(n-1). a(n) = b if b is a prime; otherwise a(n) = a(n-1) and a(n-1) = b.at n=33A346957
