i.i.d.?

infinitely long sequences? Is p a measure for the correlation of infinitely many X_i? Is X on the left side a typical string? Is there a limit involved?

Given a naural number n, what is number d(n) of possible divisors of that number.

For example 12=2*2*3, so the divisors are 2, 3 and 6, i.e. d(12)=3. Notice that 2*3 doesn't count twice, so it's not just the number of subsets of the prime factors (which would be 2^3).

To keep the notation clear, one might talk about p(n), the number of prime factors, p(n,i), the i-th distince prime factor, and p(n,i,m), the multiplicity of the i-th distince prime factor.
