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 re: Far too less - assumptions right? by brianjn)

My basic assumptions were correct.  I had the potential for the solution within my spreadsheet but my said manipulations never seemed that they would ever suggest the required layout.

My sheet is without fault! Whew!

At this point I haven't fathomed how I should have manipulated.

I did enjoy this Charlie, not sure that I'd have gotten there in all honesty!
