Square pairs (Posted on 2005-01-09) Difficulty: 3 of 5
Back in 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.

"Shouldn't the sum of all 32 sums be 2*(32*33/2)=32*33=1056?"

Yes, of course you are right.   I am an EEEEEdeeoote, as Ren would say.  That's what I get for attempting math without my morning coffee.
