%N The smallest term of A273379 having n primes between two consecutive prime divisors.

%C Is this sequence infinite?

%C In the prime factorization of a(n), the 'gap' occurs before the largest prime divisor. For example, 4680 has distinct prime divisors 2, 3, 5 and 13. The gap is before the largest prime 13. All primes up to and including the second largest prime are a divisor of a(n).
