If n=8 then the value of the Schultz molecular topological index, MTI, is 6.
If n=9 then the value of the Schultz molecular topological index, MTI, is 19.
If n=10 then the value of the Schultz molecular topological index, MTI, is 59.
If n=11 then the value of the Schultz molecular topological index, MTI, is 184.
