• Numbers n with the property that n=a-b where a has the digits of n in descending order and b has the digits of n in ascending order (perhaps with leading zeros), ordered by a.at n=4A055160
• Fixed points of the Kaprekar mapping f(n) = n' - n'', where in n' the digits of n are arranged in descending, in n'' in ascending order.at n=5A099009
• Smallest member of cycle corresponding to n-th term of A151964.at n=13A151965
• Consider the Kaprekar map n->K(n) defined in A151949. Sequence gives least elements of each cycle, including fixed points.at n=11A164718
• Subsequence of fixed points A099009 of the Kaprekar mapping with numbers of the form 6//3(n)//17//6(n)//4.at n=2A214556
