Higher-dimensional arrays?

SeqFans,
The EIS has many entries which are square arrays, and they're normally
entered by antidiagonals. But does it have any entries which are cube
(or hypercube) arrays? If not, I wonder why. I would have thought that
there would already have been many such entries!
BTW, for cube arrays,
http://www.research.att.com/~njas/sequences/A056558
states that 'Together with A056559 and A056560 might enable reading
"by antidiagonals" of cube arrays as 3-dimensional analogue of A002262
and A025581 with square arrays.'
Similarly, for hypercube arrays, there is
