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

(15−11, 15, 16299)-Net in Base 128 — Upper bound on s

There is no (4, 15, 16300)-net in base 128, because

1 times m-reduction [i] would yield (4, 14, 16300)-net in base 128, but
- the generalized Rao bound for nets shows that 128^mÂ â‰¥ 316991 077518 409506 979331 077946 > 128¹⁴ [i]
