Your task is to place the consecutive series 1 to 14 around this heptagon, using one number to each circle, such that each of the seven sides (of three circles) adds up to a constant of 26. It's quite a tough proposition, so I have correctly placed the 14 already, to give you a start.
Obviously each of the seven numbers occupying the seven nodal circles will be counted twice. The other seven interior circles will be counted once.
