- In
graph theory, a
circulant graph is an
undirected graph acted on by a
cyclic group of
symmetries which takes any

Cayley graphs of
cyclic groups with
arbitrary generator sets are
called circulant graphs.
These graphs may be
represented geometrically as a set of equally...

circulant matrix is
manifestly regular, and
therefore a
circulant Hadamard matrix would have to be of
square order. Moreover, if an n × n
