[seqfan] Re: Initial Digits of Ternary Pi

I'm sure somebody should double check this, but here goes...

Note that after 3n steps on a random walk, the chance that all three
random options (0,1,2) would be equally balanced is equal to:

    (3n)! / n! / n! / n! / 3^(3n)

Using Stirling's approximation, this is asymptotic to:


or about 0.276/n.

That does diverge of course, so there should be an infinite
number of times that the three digits balance.
