To speed up the program, it seems is optimum (Paul made a good call there) to choose the corners as the independent variables. This makes the first 6 equations to try also the shortest (3 elements), fastest, and completely decoupled, only dependent on the 6 known variables. This allows for quickly discarding a lot of cases.
The 7th variable needs to be in the inner hexagon, but not the center (choosing the center results in coupled equations, so you can't solve all variables one by one without working out the algebra to decouple the equations first).
I'll see if I can rework the RPL code to work with this new numbering scheme and will report on the speed improvement.
