Re: How many six digits
Hi tony123;
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: How many six digits
Hi;
Good to see you! You are right 125 is an extra solution that does not fit. The method I used came up with all the solutions not just the six digit ones.
I have added that fact to the original post. Appears I just made a silly mistake of being unable to count to 6 correctly.
