%N A060600 Number of tilings of the 8-dimensional zonotope constructed from D vectors.
%C A060600 The zonotope Z(D,d) is the projection of the D-dimensional hypercube onto the d-dimensional space and the tiles are the projections of the d-dimensional faces of the hypercube. Here d=8 and D varies.
%C A060600 Also the number of signotopes of rank 9. A signotope of rank r is a mapping X:{{1..n} choose r}->{+,-} such that for any r+1 indices I={i_0,...,i_r} with i_0 < i_1 < ... < i_r, the sequence X(I-i_0), X(I-i_1), ..., X(I-i_r) changes its sign at most once (see Felsner-Weil reference). - _Manfred Scheucher_, Feb 09 2022

%F A060600 Asymptotics: a(n) = 2^(Theta(n^8)). This is Bachmann-Landau notation, that is, there are constants n_0, c, and d, such that for every n >= n_0 the inequality 2^{c n^8} <= a(n) <= 2^{d n^8} is satisfied. - _Manfred Scheucher_, Sep 22 2021
%e A060600 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.
