Properties

Appears in sequences

• a(0) = 1; for n>0, a(n) = smallest prime of the form k*a(n-1) + 1.at n=10A061092
• Let f(n) be the smallest prime == 1 mod n (cf. A034694). Sequence gives triangle T(j,k) = f^k(j) for 1 <= k <= j, read by rows.at n=27A083809
• a(n) = f^(n) (n), where f(n) is the smallest prime == 1 mod n (cf. A034694).at n=6A083810
• Primes p in A109982 such that the index of p is itself a member of A109982.at n=25A109985
• Prime numbersat n=91513
