%N Values of n such that in the interval centered at A002110(n) = n-th primorial and of radius ceiling(log(center)) there is a single prime.
%C Neighborhoods of most primorials (=center) are either empty or contain few primes. In the listed few cases a single prime arises if radius=ceiling(log(center)).
%e n=6: around 30030 the prime in question is 30029.
%Y Cf. A096509-A096523, A096830-A096840, A002110.
