**The question is to find the resistance between points A and F.**

I understand that the resistor between OC can be removed. From this point onwards, resistor OC has been removed. Let the far right point of the diagram, where i5 and i7 exit from, be B.

Is it possible to detach the remaining circuit at O, such that FOA and DO'B become separate, and then resolve the remaining resistors? Why is it not possible to detach the remaining circuit at O, to form FOD and AO'B? What exactly is the reason why we can detach some circuits?
