Re: [math-fun] Ambiguously placed cities

Let the road lengths be arranged [AB, BC, CA, BD, AD, CD], where A,B,C,D denote cities. Then the follwoing two charts are distinct and planar, and both permute the same set of integers: [5, 8, 13, 11, 9, 17] [5, 17, 13, 11, 9, 8] [Given my capacity for wishful thinking, not to mention Maple's for wishful computation, I'd appreciate somebody verifying this independently!] Fred Lunnon
