Mersenne: prove

1999-04-12 Thread Benny.VanHoudt
Hi Cyril, The fact that there exists a period for your procedure (whatever the number of digits might be) is rather easy. Indeed, say you start with a n-digit number than after just a single step you get another n-digit number and so on. As there are only 10^n n-digit numbers you always obtain

Hi all, I''m searching a prove of a little problem. You take a four digit number where not all digits are equal such 5957 and reorder the digits such that the biggest digit is at the first place, the second at the second place etc. Then subtract the smallest possible reoredering from the the
