  A countable set of quantum superintegrable systems for arbitrary spin is
solved explicitly using tools of supersymmetric quantum mechanics. It is shown
that these systems (introduced by Pronko, J. Phys. A: Math. Theor. 40 (2007) )
include matrix shape invariant potentials classified recently in A. G. Nikitin
and Y. Karadzhov, J. Phys. A: 44 (2011) 305204; J. Phys. A: 44 (2011) 445202.
