sesducentagonal
Sesducentagonal refers to a polygon with 620 sides. The term is derived from Latin and Greek roots, where "ses" likely indicates a progression or addition, "ducenti" means two hundred, and "gonal" relates to angles or sides. Therefore, sesducentagonal literally translates to something akin to "added two hundred-sided" or a further progression of sidedness beyond ducentagonal (200-sided).
A sesducentagonal polygon, like any polygon, is a closed two-dimensional shape made up of straight line segments
The exterior angle of a regular sesducentagonal polygon is 360 / n, which for 620 sides is approximately
