%N Inequivalent coverings of a cubic board with the minimal number of knights.
%C This sequence is a 3-dimensional analog of A006076.
%C Sequence A110214 gives minimal number of knights needed to cover an n X n X n board. This sequence gives the number of inequivalent solutions to cover an n X n X n board using A110214(n) knights.
%F a(n) = A110218(n, n, n).
%e a(3) = 1, since up to rotations and reflections,
