Ah right, so that would be a 3D array.

T* is a single row of T
T** is a list of rows
T*** is a list of "layers" in the third dimension

This would be incredibly hazardous to pass around as a bare pointer with no context, though. I'd expect to see this in a struct that, at minimum, also includes fields for the size of each dimension.
