Superintegrability and Kontsevich-Hermitian relation

We analyze the well-known equivalence between quadratic Kontsevich-Penner and Hermitian matrix models from point of view superintegrability relations, i.e. explicit formulas for character averages. This is not that trivial on Kontsevich side, seems important further studies various deformations models. In particular, Brezin-Hikami extension above becomes straightforward.
