(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A151834 Number of fixed 8-dimensional polycubes with n cells. 3
1, 8, 120, 2276, 49204, 1156688, 28831384, 750455268, 20196669078, 558157620384, 15762232227968, 453181069339660 (list; graph; refs; listen; history; text; internal format)



a(1)-a(10) can be computed by formulas in Barequet et al. (2010).  Luther and Mertens confirm these values (and add two more) by direct counting.
