Four routers have to be interconnected in a point-to-point Network. Each pair of root us may connected by a high-speed line, a medium speed line or a low speed line. Find the total number of topologies.

                Just use simple Formula  n(n-1)/2.
As we know that there are 4 routers so put values in above formula.
4(4-1)/2 = 6 :-which means that there will be 6 point to point channels and (4-1) which is 3 will denote maximum number of point to point connection each router could have.
So, finnally 3^6 = 729.
