Idea

There is, by the brane scan, a superstring propagating in the 6-dimensional worldvolume of an NS5-brane. This is often called the little string, with respect to the superstrings in the ambient 10-dimensional heterotic supergravity and type II supergravity that in turn the NS5-brane is propagating in.

The scan.

The super pp- (see at for further links and see at for the full classification):
