In this work we study stably rationally connected threefolds which are not rational. The first example of such variety was introduced by M.\,Artin and D.\,Mumford, it was a nodal quartic double solid branched over a quartic with 10 nodes. Then S.\,Endrass was showed that Artin——Mumford family of quartic is unique with non-trivial Artin-Mumford obstruction in the class of nodal quartics. We are going to consider sextic double solids. We specify the minimal type of sextic surfaces, such that the double solid has a non-trivial obstruction and then study double solids of minimal type.
