%N A100188 Polar structured meta-anti-diamond numbers, the n-th number from a polar 
               structured n-gonal anti-diamond number sequence.
%F A100188 a(n)=(1/6)*(2*n^4-2*n^2+6*n)
%e A100188 There are no 1- or 2-gonal anti-diamonds, so 1 and (2n+2) are the first 
               and second terms since all the sequences begin as such.
%Y A100188 Cf. A000578, A000447, A004466, A007588, A063521, A062523 - "polar" structured 
               anti-diamonds; A100189 - "equatorial" structured meta-anti-diamond 
               numbers; A006484 for other structured meta numbers; and A100145 for 
               more on structured numbers.
