COMMENT

Together with A127324, A127325, and A127327 might enable reading "by antidiagonals" of hyper-cube arrays as 4-dimensional analogue of A056558, A056560 and A056559 with cubical arrays.

FORMULA

a(n)=A127322(n)-A127323(n)

EXAMPLE

a(23)=0 because A127322(23)-A127323(23)=0

See A127327 for a table of A127324, A127325, A127326, A127327
