  We calculated the critical temperature in the framework of s+-+d-wave
multiband Eliashberg theory. We have solved these equations numerically to see
at what values of the input parameters there is a solution with a non-zero
critical temperature and what is the symmetry of the order parameter of this
solution. For our model we consider the pnictide case with simplifications that
allow us to obtain the most general possible information. For selected and
representative cases in which the order parameter has s+-+d symmetry, we
calculated the superconducting density of states, the temperature dependence of
the gaps, and the superfluid density so that comparison with experimental data
can be made. Finally, we show that such a system has only a twofold in-plane
symmetry and undergoes a transition from nodal to fully gapped with increasing
temperature.
