OEIS Sequences

a(n) = 10 + floor( (1 + ∑_j=1..n-1 a(j) )/3 ). A120155

Number of prime parts in the partitions of n into 8 parts. A309437

G.f. satisfies A(x) = 1 + x·cycle_index(G,A(x)) where G = cyclic group of order 17 generated by (1,2,...,17). A36731

Consider the base-6 Kaprekar map n->K(n) defined in A165051. Sequence gives numbers belonging to cycles, including fixed points. A165056

Consider the base-6 Kaprekar map n->K(n) defined in A165051. Sequence gives numbers belonging to cycles of length greater than 1. A165058

Smallest member of cycle corresponding to n-th term of A165068. A165069

Consider the base-6 Kaprekar map n->K(n) defined in A165051. Sequence gives least elements of each cycle, including fixed points. A165060

Consider the base-6 Kaprekar map n->K(n) defined in A165051. Sequence gives least elements of each cycle of length > 1. A165062

Consider the base-6 Kaprekar map x->K(x) described in A165051. Sequence gives the smallest number that belongs to a cycle of length n under repeated iteration of this map, or -1 if there is no cycle of length n. A165067

Numbers k such that the continued fraction for sqrt(k) has even period and if the last term of the periodic part is deleted the central term is 35. A31533
