  Examples of non-trivial higher string topology operations have been
regrettably rare in the literature. In this paper, working in the context of
string topology of classifying spaces, we provide explicit calculations of a
wealth of non-trivial higher string topology operations associated to a number
of different Lie groups. As an application of these calculations, we obtain an
abundance of interesting homology classes in the twisted homology groups of
automorphism groups of free groups, the ordinary homology groups of holomorphs
of free groups, and the ordinary homology groups of affine groups over the
integers and the field of two elements.
