Properties

Appears in sequences

• a(0) = 1; for n>0, a(n) = smallest prime of the form k*a(n-1) + 1.at n=9A061092
• 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=26A083809
• Triangle read by rows: n-th row begins with n and contains n terms with the same prime signature such that the (r+1)-th term == 1 (mod r-th term).at n=27A113031
• Prime numbersat n=48360
