So, first of all, here is a drawing of a circuit:

The resistance of each hexagon wire is r.

I need to find the resistance of this circuit when it is connected to the source with points A and B.

I know that in this case I need to find the points in the circuit which potentials are equal. Then I should be able to simplify this circuit and find out the resistance of it.

So I know what I have to do, but I don't know how to do it. I have tried searching the internet, but I haven't found any resourses which explain the process.

Do you know any resources, articles or something similar which explain how to find the points in the circuit which have the same potentials?

Any help or suggestion would be appreciated.
