Resistance calculation in a cube

[cooltwins]

Homework Statement

each edge of a cube is built with a one ohm resistor, body diagonals are also built with one ohm resistors each. find out equivalent resistance across any two adjacent vertices.

Homework Equations

i guess it deals with star and delta transformations

The Attempt at a Solution

i'm attempting the question at the present and will post my solution once I'm done with the question.

hoping for a reply from you,

hay..

just look at the network. here resistor a,b, and c(color green) are parallel and d,e,f,g,h,i(blue) are in parallel and j,k,l(red) are parallel in figure 1. While all these(green-blue-red) are connected in series. Look figure 2.
