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

(9, 9+15, 46146)-Net in Base 64 — Upper bound on s

There is no (9, 24, 46147)-net in base 64, because

1 times m-reduction [i] would yield (9, 23, 46147)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 348467 727527 527238 960304 027237 620873 106880 > 64²³ [i]
