%N A116600 a(n) = A011782(n) + A000219(n) - A000712(n).
%C A116600 Old definition was "Counts compositions plus plane partitions less partitions into parts of two kinds".
%C A116600 A116600 is essentially A115981 + A115982 since A000712 = A001523 + A006330.
%F A116600 a(n) = A011782(n) + A000219(n) - A000712(n).
%e A116600 a(8) = 103 because A011782(8) + A000219(8) - A000712(8) = 128 + 160 - 185.
