Hints
(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A155463 Largest element of a set of n primes with the property that the pairwise averages are all distinct primes, having the smallest largest element (A115631). 0
7, 19, 71, 173, 383, 881, 2111, 5417, 10691, 21757, 27611 (list; graph; refs; listen; history; text; internal format)

2,1

COMMENTS

The solution for n=5 is {5, 29, 53, 89, 173}, so a(5)=173. This sequence is not proved to be optimal, so smaller terms may exist.
