look for star-triangle conversion, thats the easy way to get it done, when you do the conversion you will end with 2 series, and these 2 series will be paralel to each other, and this paralel in serie with the last one

What is a "star-triangle conversion"? I've heard of star (wye) and triangle (delta) in three phase transformers, but what is star and triangle in resistances?

Yup just like tsukiumy said either the top delta or the lower delta must be converted to star to be able to reduce the network, fo

For example if you convert the lower delta you'll get a circuit like the one on the left, http://everycircuit.com/circuit/6066841254625280
