  It has been demonstrated, in a number of special situations, that the spin
coefficients of a canonical spinor dyad can be used to define a Lanczos
potential of the Weyl curvature spinor. In this paper we explore some of these
potentials and show that they can be defined directly from the spinor dyad in a
very simple way, but that the results do not generalize significantly, in any
direct manner. A link to metric, asymmetric, curvature-free connections, which
suggests a more natural relationship between the Lanczos potential and spin
coefficients, is also considered.
