For an integer n \geqslant 3 we define the sequence \alpha_1, \alpha_2, \ldots, \alpha_k as the sequence of exponents in the prime factorization of n! = p_1^{\alpha_1}p_2^{\alpha_2} \ldots p_k^{\alpha_k}, where p_1 < p_2 < \ldots < p_k are primes. Determine all integers n \geq 3 for which \alpha_1, \alpha_2, \ldots, \alpha_k is a geometric progression.
