Re Kaprekar ... Dear Mauro, It appears that below comment made by Jens Kruse Andersen in https://oeis.org/A099009
Let d(n) denote n repetitions of the digit d. The sequence includes the following for all n>=0: 5(n)499(n)4(n)5, 63(n)176(n)4, 8643(n)1976(n)532 . - Jens Kruse Andersen, Oct 04 2004
is missing one more family of terms: 97508421,9753086421, 9975084201, 975330866421, 997530864201, 999750842001, ... May be it could be generalized (using the same method of notations as in Jens comment) as 99(n)7(k)53(m)086(m)42(k)0(n)1 ? What do you think ? Alexander R. Povolotsky (Apovolot at gmail dot com)
