Abstract Recently, Che and Wu (2019 Int. J. Theor. Phys. 58 584–90) presented a recurrence relation of multi-qubit states. Inspired by this, we present the recurrence relation of ququart maximally entangled states. Further, via the recurrence relation of six ququarts maximally entangled states, a seven ququarts absolutely maximally entangled state can be constructed. We also show this state is the three-uniform state of seven ququarts states.
