(257−105, 257, 109)-Net over F₂ — Digital

Digital (152, 257, 109)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(257−105, 257, 540)-Net in Base 2 — Upper bound on s

There is no (152, 257, 541)-net in base 2, because

1 times m-reduction [i] would yield (152, 256, 541)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 122899 712524 260357 858133 247789 015399 230090 618749 050904 605129 318893 351400 829392 > 2²⁵⁶ [i]
