Abstract
The following comment is based on an article by Jafarpour and Assadi (Eur. Phys. J. D 70, 62 2016) which with an exploitation of Scott measure (or generalized Meyer-Wallach measure) the entanglement quantity of four-qubit graph states has been calculated. We are to reveal that a 2-2 partition necessarily always does not provide a stronger entanglement than a 3-1 partition in all the graph states.
