Neighbourhoods of most primorials[=center] are either empty or poor of primes. The listed primes arise if center=A002110[A096833(n)], while radius=Ceiling[Log[center]].

The subsequent terms are too large to include: a(6) = A002110(66)-1, which has 131 digits. a(7) = A002110(68)-1, which has 136 digits. a(8) = A002110(75)+1, which has 154 digits. - David Wasserman (dwasserm(AT)earthlink.net), Nov 16 2007
