        Is this the smallest golygon?

        Due to the constraint of right angle & non-equal sides, the smallest golygon must have eight sides with additional constraints that two sides must have same sum as two sides parallel to it; and similarly for 4 other sides. Here, 7+1=5+3 and 8+2=6+4; and set of sides ={i| 1<=i<=8}

        This was anticipated in 1639 by mathematician Gunter Krappenpuhl (1602-1684) who crafted a polygon with 28 sides each of which represented the ages of his many children. He called the figure a “condomgon.”
