Prime Magic Square (Posted on 2011-08-04) Difficulty: 3 of 5
S U R F C A L M E X P O T I N Y

Each of the above letters represents a positive integer smaller than 200. In some order they represent an arithmetic sequence. Overall, the grid as presented is a magic square, with each row, each column and each of the two large diagonals adding to the same value.

Also, each of the letters in P-R-I-M-E-S represents a prime number, and in themselves they also form an ascending arithmetic sequence, in the order P-R-I-M-E-S.

What is this magic square?

(In reply to Far too less -observations and thoughts by brianjn)

The more I play the more I feel that my assumptions of the interval being 6 or 12 are likely to be incorrect.

That said I still cannot arrive at a magic square (using numerals from 1 to 16) where "P-R-I-M-E-S" forms an AP in ascending order.
