We do not begin with the unit 1 because it has no prime factors. Conjecture: The sequence contains the set of prime numbers more than once.
FORMULA
The geometric mean is the n-th root of the product of n numbers.
Gm = (a(1)*a(2)*...*a(n))^(1/n).
EXAMPLE
12=2*2*3 has 3 factors; 12^(1/3) = 2.289428... so 2 is in the 11th position in the sequence.
PROG
(PARI) g(n) = for(x=2, n, print1(floor(x^(1/bigomega(x)))", "))
