%N Number of ways to dissect a nonsquare rectangle into n rectangles of equal area up to symmetry.
%e There are 4 ways (up to symmetry) to form a nonsquare rectangle from 3 rectangles with the same area:

%e So a(3)=4.
%e The eleven solutions for n=4 can be seen as a subset of the illustration of A189243(4) = 21 in that entry. - _N. J. A. Sloane_, Dec 05 2012
