%N Sum of omega(n!) and bigomega(n!).

%C omega(x!) = number of primes <= x or Pi(x)

%F omega(x): number of distinct prime divisors of x. bigomega(x): number of prime divisors of x, counted with multiplicity.

%o (PARI) omegafactpbigomegafact(n) = { local(x); for(x=0,n, print1(omega(x!)+bigomega(x!)",") ) }
