An Arrangement of 15 you were asked to place the numbers 1 to 15 in a line so that any two adjacent numbers summed to a square number.

Now, try to arrange the numbers from 1 to 32 in a *circle*, so any two adjacent numbers again sum a square number.

This has really motivated me to try some programming to find out whether there is a general correspondence to any integer from 1....May be this is much involved job using large computation even with a computer....lots of permutations and combinations to tryout I think.
