randomUniformHyperGraph -- returns a random uniform hypergraph

Synopsis

Description

This function allows one to create a uniform hypergraph on an underlying vertex set with a given number of randomly chosen edges of given cardinality.

i1 : R = QQ[x_1..x_9];
i2 : randomUniformHyperGraph(R,3,4)

o2 = HyperGraph{"edges" => {{x , x , x }, {x , x , x }, {x , x , x }, {x , x , x }}}

                "ring" => R
                "vertices" => {x , x , x , x , x , x , x , x , x }
