[quadrata]

Here's a puzzle I just made on the graph GP(8,3). Enter 1 through 8 into the large circular cells so that each number appears twice. Adjacent cells must contain different numbers. The clues between cells reveal the sum of those two cells. Numberless clues indicate that the sum is larger than eight without revealing that sum.
