Abstract
The first Zagreb index of a graph G is the sum of squares of the degrees of the vertices of G. Expressions for the first Zagreb index and first Zagreb coindex are obtained for total, semitotal-line (or middle), and semitotal-point graphs, as well as of eight distinct types of total transformation graphs Gxyz.
