Nonlinear building blocks with three 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:
| 3-functional groups: 0 to 3
| 2-functional groups: 4 to 9
See :class:`.Cage` for more details and examples.
