1. the picture does not show a circuit.
2. the picture does not show the two points that the resistance is to be taken between.
3. there appears to be a short-circuit between the left and right-most extreme nodes.
Once the above issues are sorted out - you will find the total resistance by simplifying the circuit. It can help to redraw it.
I don't see any symmetry that would help you out here so it seems to me you'll just have to do a ton of delta-Y transforms and simplify the circuit bit by bit. Looks to conceptually trivial but VERY messy to actually carry out.
