Has it been proven that no similar number exists in base 10 with 5+ digits. My current conjecture is that this is right. Georgia guy 22:38, 17 July 2007 (UTC)

It has been proven that no similar number exists for 5-digit numbers. This link (the first link under External links section) discusses the result of Kaprekar's operation for 2-digit to 10-digit numbers. Gaurav1146 11:12, 19 July 2007 (UTC)
