OEIS Sequences

a(n) = number of steps to reach 0 when starting from k = (n³)-1 and repeatedly applying the map that replaces k with k - A055401(k), where A055401(k) = the number of positive cubes needed to sum to k using the greedy algorithm. A261228

a(n) = floor(Fibonacci(n)/5). A4698

Triangle read by rows, k!*s₂(n, k) where s_m(n, k) are the Stirling-Frobenius cycle numbers of order m; n >= 0, k >= 0. A225475

a(0) = 1, a(n) = 21·n² + 2 for n>0. A10011

a(n) = sum of terms of {a(1),a(2),a(3),...a(n-1)} which are coprime to n. A96217

a(n) = floor(L³*{φ^3·n-2, φ^3·n-1, φ^3·n-2 + φ^3·n-1}) where L = (1 + sqrt(5))/(2·sqrt(5)) and φ = (1 + sqrt(5))/2. A115315

a(n) = ∑_k=1..n k·k', where n' is the arithmetic derivative of n. A190117
