OK I make it 16. If there are four variables ie Small Male (SM), Small Female (SF), Large Male (LM) and Large Female (LF) and the cable length is constant then the result is 2 to the power 4 or 16. I don't see how you can account for different lengths of cable though as you don't know how far apart the equipment is going to be so a cable that is 1 mile long could still join two pieces of equipment that are only a foot apart. Now tell me I am missing something..... Tomorrow, I am off to bed.
