Re: [math-fun] Add no digit of n to n

So this finite sequence has 65627501 terms? Or maybe 65627502? Jim On 12/10/06, Michael Kleber <michael.kleber@gmail.com> wrote:

What did we do before computers could do millions of pointless calculations for us?...

Hello Math-Fun,

What is the last term of the sequence starting with "1" and obeying the rule:

"Add to n the smallest positive integer sharing no digit with n"

Sequence should begin like this :

1,3,4,5,6,7,8,9,10,12,15,17,19,21,24,25....

Best,

E.
