(195−71, 195, 395)-Net over F₄ — Digital

Digital (124, 195, 395)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(195−71, 195, 10047)-Net in Base 4 — Upper bound on s

There is no (124, 195, 10048)-net in base 4, because

1 times m-reduction [i] would yield (124, 194, 10048)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 632 492460 273313 891735 425100 986080 430413 378672 251065 026882 793931 127373 196351 383604 212381 048110 161811 158140 764666 969947 > 4¹⁹⁴ [i]
