OEIS Sequences

A(n,k) is (1/n) times the n-th derivative of the k-th tetration of x (power tower of order k) x^^k at x=1; square array A(n,k), n>=1, k>=1, read by antidiagonals. A295028

a(n) is the smallest k such that A342068(k) = n. A342069

a(n) is the numerator of (120·n² + 151·n + 47)/(512·n⁴ + 1024·n³ + 712·n² + 194·n + 15). A374580

a(n) = (1/n) times the n-th derivative of the third tetration of x (power tower of order 3) x^³ at x=1. A295103
