Query: Second-order linear differential equations associated to a Riccati
  equation of constant coefficients   We present several second-order linear differential equations that are
associated to a particular Riccati equation with only one constant parameter in
its coefficients through the technique of supersymmetric factorizations and
through a Dirac-like procedure. The latter approach is a minimal extension of
the results obtained with the first technique in the sense that it includes up
to two more constant parameters
