In this paper we give some evidence that this desert continues up to index 3+\\sqrt{5}. There are two known quantum-group subfactors with index in this interval, and we show that these subfactors are the only way to realize the corresponding principal graphs. One of these subfactors is 1-supertransitive, and we demonstrate that it is the only 1-supertransitive subfactor with index between 5 and 3+\\sqrt{5}. Computer evidence shows that any other subfactor in this interval would need to have rank at least 38.
