The topological Zagreb index M-1 introduces an ordering on the set of alkanes. Recently, modified Zagreb indices M-lambda(1) have been proposed, and it is noted that they differently order alkanes. In this paper, the level of consistency between these orders is analyzed. A new partial order > as the intersection of all partial orders M-lambda(1) (where m is at least 2) is introduced and its properties are analyzed.
