# 209173

This number is a prime.

The start of the longest known chain of super magic primes, i.e., with each of its subsets having a distinct prime average (209173, 322573, 536773, 1217893, 2484733), although the Green-Tao theorem predicts the inexistence of an upper bound to the length of such chains. [Beedassy]
