convexHullEdges→False is an option for convexHullFormat

convexHullEdges is only used in three-dimensional data sets, and is not valid for two-dimensional data sets.

If convextHullEdges→True then the retun value (an option list) of convexHull includes a list of vertex-index-pairs of the form

convexHullEdges→{{i1,j1},{i2,j2},...}
Each pair {i, j} describes an edge of the convex hull, i.e., there is an edge from point i to point j. The pairs returned are sorted in lexicagraphical order and with i (the first index of each pair) < j (the second index of each pair).
