    Nonlinear building blocks with four functional groups are
    required for this topology.

    Linear building blocks with two functional groups are required for
    this topology.

    When using a :class:`dict` for the `building_blocks` parameter,
    as in :ref:`cage-topology-graph-examples`:
    *Multi-Building Block Cage Construction*, a
    :class:`.BuildingBlock`, with the following number of functional
    groups, needs to be assigned to each of the following vertex ids:

        | 4-functional groups: 0 to 5
        | 2-functional groups: 6 to 17

    See :class:`.Cage` for more details and examples.
