%N A306096 Number of plane partitions of n where parts are colored in (at most) 6 colors.
%C A306096 a(0) = 1 corresponds to the empty sum, in which all terms are colored in one among six given colors, since there is no term at all.
%H A306096 M. F. Hasler, <a href="/A306096/b306096.txt">Table of n, a(n) for n = 0..50</a>
%F A306096 a(n) = Sum_{k=1..n} A091298(n,k)*6^k, for n > 0.
%e A306096 For n = 1, there is only the partition [1], which can be colored in any of the six colors, whence a(1) = 6.
%e A306096 For n = 2, there are the partitions [2], [1,1] and [1;1]. Adding colors, this yields a(2) = 6 + 36 + 36 = 78 distinct possibilities.
%o A306096 (PARI) a(n)=sum(k=1,n,A091298(n,k)*6^k,!n)
%Y A306096 Cf. A091298, A208447.
%Y A306096 Column 6 of A306100 and A306101. See A306099, A306093, A306094, A306095 for columns 2, 3, 4 and 5.
