A multigraph has two sorts of elements forming a set V of vertices and E of edges, and has two unary operations s,t: E → V giving the source (start) and target (end) vertices of each edge. Source: Internet
Many authors call this type of object a multigraph or pseudograph. Source: Internet
What is special about a multigraph as an algebra is that its operations are unary. Source: Internet
