65535 is the fifteenth 626- gonal number, the fifth 6555-gonal number, and the third 21846-gonal number. 65535 is the product of the first four Fermat primes: 65535 = (2 + 1) (4 + 1) (16 + 1) (256 + 1). Because of this property, it is possible to construct with compass and straightedge a regular polygon with 65535 sides (see, constructible ...
