(143, 232, 115)-Net over F₂ — Digital

Digital (143, 232, 115)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(143, 232, 593)-Net in Base 2 — Upper bound on s

There is no (143, 232, 594)-net in base 2, because

1 times m-reduction [i] would yield (143, 231, 594)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 3455 287337 481969 854410 702281 226198 545966 151409 013317 676111 989457 320840 > 2²³¹ [i]
