%N A set of 25 consecutive primes that form a 5 X 5 magic square with the (non-minimal) magic constant 1703.
%C The magic constant here is not the smallest possible for a 5 X 5 magic square composed of consecutive primes, this would be A073520(5) = 313 corresponding to primes (13, 17, ..., 113). [Edited by _M. F. Hasler_, Oct 29 2018]
