The calculation of the adjacency indices of type $D$ singularities of a front

The formula for the calculation of the adjacency indices of types $D_{\mu }^{\pm }$ Legendrian monosingularities to multisingularities of types $A_{{\mu }_1}^{k_1}\dots A_{{\mu }_p}^{k_p}$ is obtained in the paper. Namely the number of strata of a given type $A_{{\mu }_1}^{k_1}\dots A_{{\mu }_p}^{k_p}$ in the discriminant of a real simple singularity of any of types $D_{\mu }^{\pm }$ is calculated.
