The topological Zagreb index M 1 introduces an ordering on the set of alkanes. Recently, modified Zagreb indices λ M 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 λ M 1 (where m is at least 2) is introduced and its properties are analyzed.
