networks

 icosahedron
 creates an icosahedron graph

 Calling Sequence G:=icosahedron()

Parameters

 G - is returned as the icosahedron

Description

 • Important:The networks package has been deprecated. Use the superseding command GraphTheory[SpecialGraphs][IcosahedronGraph]instead.
 • The simple graph known as a icosahedron is generated and returned as the value of the procedure call.
 • This routine is normally loaded via the command with(networks) but may also be referenced using the full name networks[icosahedron](...).

Examples
