Hypercubic numbers
From OeisWiki
Since cube numbers refer to 3-dimensional figurate numbers, hypercube numbers refer to n-dimensional figurate numbers for n greater than 3.
Cubic numbers refer to algebraic numbers of 3rd degree, and hypercubic numbers would/should then refer to algebraic numbers of nth degree for n greater than 3, but there is no such usage...
So, you probably meant hypercube numbers.
