Hendecagon of a regular hendecagon is still impossible even with the usage of an angle trisector. It can, however, be constructed via neusis construction and also via two-fold origami. Close approximations to the regular hendecagon can be constructed, however. For instance, the ancient Greek mathematicians approximated the side length of a hendecagon inscribed in a unit circle as being 14/25 units long. The following construction description is given by T. Drummond from 1800: On a unit circle: The "regular hendecagon" has Dih symmetry, order 22. Since 11 is a prime number there is one subgroup with dihedral symmetry: Dih, and 2
How Many Miles to Babylon? In the 1824 edition of "The Scottish Gallovidian Encyclopedia" there's a description of the rhyme and the game, giving the distance as "six, seven or a lang eight". The rhyme was originally accompanied by a singing game in which two lines face each other, with one player in the middle.
