M. Latapy, Tilings of Zonotopes

For any d, the only possible tile for Z(d,d) is Z(d,d) itself, therefore the first term of the series is 1. It is well known that there are always two d-tilings of Z(d+1,d), therefore the second term is 2. More examples are available on my web page.

Cf. A006245 (two-dimensional tilings), A060595-A060602. A diagonal of A060637.
