This paper studies the birational geometry of terminal Gorenstein Fano 3-folds. IfYis not-factorial, in most cases, it is possible to describe explicitly the divisor class group ClYby running a Minimal Model Program onX, a small-factorialization ofY. In this case, the generators of ClY/ PicYare “topological traces” ofK-negative extremal contractions onX. One can show, as an application of these methods, that a number of families of non-factorial terminal Gorenstein Fano 3-folds are rational. In particular, I give some examples of rational quartic hypersurfaceswith rk ClY= 2 and show that when rk ClY≥ 6,Yis always rational.
