Assuming cities are a, b,c,d,e,f, they will form a circlular connection.

So, 6 bidirectional links or 12 one directional links.

I am not saying circular, by bidirectional I mean if there is a way from A to B it is also from B to A, and by two links from A I mean to two different cities let us say B and C. Hope I am clear.

so heres how that will map out:


B -------C ------- D
! !
! !
A--------E---------F

If every city is connected to the other 2, they will form a circle (or square or something like that... :) lol). But then they will have 6 bi directional conections.

Cmon Maihuna, help me out of my misery here, tell me the answer... :)
