• Numbers k such that k and k^2 use only the digits 0, 2, 4, 6 and 9.at n=38A136905
• Consider the base-5 Kaprekar map n->K(n) defined in A165032. Sequence gives numbers belonging to cycles, including fixed points.at n=18A165037
• Consider the base-5 Kaprekar map n->K(n) defined in A165032. Sequence gives numbers belonging to cycles of length greater than 1.at n=15A165039
• Consider the base-5 Kaprekar map n->K(n) defined in A165032. Sequence gives least elements of each cycle, including fixed points.at n=7A165041
• Consider the base-5 Kaprekar map n->K(n) defined in A165032. Sequence gives least elements of each cycle of length > 1.at n=4A165043
• Consider the base-5 Kaprekar map x->K(x) described in A165032. 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.at n=5A165047
