%N A061349 Sum of antidiagonals of A060736.
%C A061349 a(1)=1, a(2)=2+4=6, a(3)=5+3+9=17, a(4)=10+6+8+16=40.
%F A061349 a(n) =A005900(n)-A006918(n) =a(n-1)+A001844(n-1)-A002378(A004526(n-1)) 
               =a(n-1)+n^2+(n-1)^2-[(n-1)/2][(n+1)/2] with a(0)=0. If n is odd then 
               a(n)=(7n^3+5n)/12; if n is even then a(n)=(7n^3+8n)/12.
