Dear Sir,

do numbers with six digits >always< reach one of the kernels 549945 or 631764? I tried 789102 as an arbitrary number to start with, but my program yielded the following periodic numbers:

1. round: 987210 - 12789 = 974421
2. round: 974421 - 124479 = 849942
3. round: 998442 - 244899 = 753543
4. round: 755433 - 334557 = 420876 <-
5. round: 876420 - 24678 = 851742
6. round: 875421 - 124578 = 750843
7. round: 875430 - 34578 = 840852
8. round: 885420 - 24588 = 860832
9. round: 886320 - 23688 = 862632
10. round: 866322 - 223668 = 642654
11. round: 665442 - 244566 = 420876 <-

Is it a flaw in the program or haven't I yet correctly understood the meaning of your explanations given above?

Thank you!
