The absolutely maximally entangled (AME) states play key roles in quantum information processing. We provide an improved criterion on the existence of AME states for general dimension d of individual subsystems and number of partite n. For d = 2, our criterion excludes the existence of seven-qubit AME states, recovering the main result provided recently in [Phys. Rev. Lett. 118. 200502]. For higher dimension d and general n, our criterion significantly improves the existing results.
