RandomSample
:RandomSample cannot generate a sample of length 4​, which is greater than the length of the sample set {}. If you want a choice of possibly repeated elements from the set, use RandomChoice.
Union
:Heads RandomSample and List at positions 2 and 1 are expected to be the same.
A net for a polyhedron folds up to form a closed solid. The nets for four polyhedra are labeled. Find the face opposite the given face in the 3D solid.
