(187−67, 187, 112)-Net over F₂ — Digital

Digital (120, 187, 112)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(187−67, 187, 607)-Net in Base 2 — Upper bound on s

There is no (120, 187, 608)-net in base 2, because

1 times m-reduction [i] would yield (120, 186, 608)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 101 348820 010306 221276 583685 646747 053224 031920 767904 445274 > 2¹⁸⁶ [i]
