Give an example:
a(2) = 5 because 5#-1 = 209 and 5#+1 = 211 are both prime at the same time, and 3 is the
only prime less than 5 having this property.

Oops, what was I thinking about? It should read:

a(2) = 5 because 5#-1 = 29 and 5#+1 = 31 are both prime at the same time, and 3 is the
only prime less than 5 having this property.
