▪
The degree is : the sum of the vertex degrees of hg, minus the degree of its root vertex, which by convention is the first vertex in [hg].
ℎ𝑔=deg(ℎ𝑔)-deg(root)
▪
Vertex degrees are read from the vertex annotation, set with the option ; a vertex with no explicit degree defaults to 0.
"Degree"
"VertexAnnotationRules"{"Degree"{vd,…}}
▪
uses this degree, together with the convention, to sign the terms of its and insertion brackets, and to restrict insertion to vertices of matching degree.

A hypergraph with no annotation has degree 0:

 | Hypergraph |
Out[1]=
0

A hypergraph made only of isolated vertices also has degree 0:
