(247−95, 247, 121)-Net over F₂ — Digital

Digital (152, 247, 121)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(247−95, 247, 624)-Net in Base 2 — Upper bound on s

There is no (152, 247, 625)-net in base 2, because

1 times m-reduction [i] would yield (152, 246, 625)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 117 532511 197148 496597 504896 197312 763148 884355 775941 690182 511783 839051 339776 > 2²⁴⁶ [i]
