Consider that the coordinating atoms of the ligands in cis- $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right] \mathrm{Cl}$ and mer- $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_3 \mathrm{Cl}_3\right]$ octahedral complexes are at the vertices of an octahedron. The sum of total number of the triangular faces in both the complexes having one N atom and two Cl atoms at their corners is $\_\_\_\_$ .

The total number of all possible isomers for the square planar complex with formula

$\mathrm{K[M(NCS)(NO_2)(gly)]}$ is ______.

($\mathrm{M} = \text{metal ion and } \mathrm{gly} = \mathrm{NH_2CH_2COO^-}$)
