How can 3 coins be maximally entangled? Is there also a quantum solution to entanglement monogamy?

A 3-qubit state with this property is the |000> + |111> state. But |0000> + |1111> doesn't work as a 4-qubit state because when you cut it into evenly sized pieces you should be able to distill 2 bell pairs instead of 1.
