Gilbertâ€“VarÅ¡amov bound [i]

(100, 100+51, 13874)-Net in Base 4 — Upper bound on s

There is no (100, 151, 13875)-net in base 4, because

1 times m-reduction [i] would yield (100, 150, 13875)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 037515 743499 107305 296357 114789 078905 020650 802719 144053 597503 037144 696971 756897 744815 742616 > 4¹⁵⁰ [i]
