    "abstract": "A class of self-similar sets of entangled quantum states is introduced, for\nwhich a recursive definition is provided. These sets, the \"Bell gems,\" are\ndefined by the subsystem exchange symmetry characteristic of the Bell states.\nEach Bell gem is shown to be an orthonormal basis of maximally entangled\nelements. A non-trivial example Bell gem is presented. Quantum circuits for\nproducing the elements of this example from the computational basis states are\nprovided.",
