 flowpoly
 flow polynomial of an undirected graph Calling Sequence flowpoly(G, h) Parameters

 G - undirected graph or network h - variable used in flow polynomial (usually a modulus) Description

 • Important: The networks package has been deprecated.  Use the superseding command GraphTheory[FlowPolynomial] instead.
 • The flow polynomial in variable h gives the number of nowhere-zero flows on G with edge labels chosen from integers modulo h.
 • This routine is normally loaded via the command with(networks) but may also be referenced using the full name networks[flowpoly](...). Examples
