Setup and Rule Diagrams

[oq058420]

I'm not sure I understand this sentence:

Thus, M must be directly connected to either J or N, but it cannot be connected to both or that would be a violation of the third rule.

I don't see how M's being connected to both J and N would be a violation of the third rule, the rule that says no chalet can be directly connected to more than two chalets. In that scenario, where M, J, and N form a triangle of connections, each would be connected to two chalets only. Of course, there'd be no way to connect any of them to L or O, which would violate the "single continuous path" constraint, but I really don't see how the third rule has been violated.

Hi oq058420,

It's because of the combination of the continue single line rule and the no more than two connection rule. If M is connected to both J and N we'd have to violate the only 2 connections per variable rule in order to make a continuous line. J would be connected to N and M. N would be connected to both J and M. Either J or N would need to connect to O/L/K to make a continuous line, but they already would have their limit of two connections met. Therefore, we'd have a violation of the rules as a whole.

Hope that helps!
