Consider a star graph consisting of a central hub vertex and
spokes, but instead of placing a single point at the end of
each spoke, place
points along it (in addition to the shared central point). While this graph has been
considered by various authors, it apparently has not been given a standard name.
In this work, to avoid confusion with star graphs and permutation
star graphs, the term
spoke graph and notation
are used.
Special cases are summarized in the following table.
