COMMENTS

Together with A127324, A127325 and A127326 might enable reading "by antidiagonals" of hyper-cube arrays as 4-dimensional analog of A056558, A056560 and A056559 with cubical arrays.

LINKS

Table of n, a(n) for n=0..104.

FORMULA

a(n) = A127321(n) - A127322(n).

EXAMPLE

a(23)=1 because A127321(23) - A127322(23) = 1.
