Heptagon "r = 1 m", the absolute error of the 1st side would be "approximately -1.7 mm" The "regular heptagon" belongs to the D point group (Schoenflies notation), order 28. The symmetry elements are: a 7-fold proper rotation axis C, a 7-fold improper rotation axis,S, 7 vertical mirror planes, σ, 7 2-fold rotation axes, C, in the plane of the heptagon and a horizontal mirror plane, σ, also in the heptagon's plane.
