%N The number of sets of parallel planes into which the planes defined in A270578 fall.
%e The 20 planes defined by the points of the 2 X 2 X 2 grid fall into 13 families of parallel planes: 3 parallel to the faces, 4 perpendicular to the space diagonals and 6 which are the planes defined by an edge and its opposite edge. So a(2)=13.
%Y Cf. A222267, A270578.
