    - sharp bound on the number of rational points on curves with genus 2 [i]

(21−16, 21, 30954)-Net in Base 256 — Upper bound on s

There is no (5, 21, 30955)-net in base 256, because

the generalized Rao bound for nets shows that 256^mÂ â‰¥ 374 148244 410575 039496 531729 988319 461391 359634 461201 > 256²¹ [i]
