(90, 90+49, 1128)-Net over F₈ — Digital

Digital (90, 139, 1128)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(90, 90+49, 218274)-Net in Base 8 — Upper bound on s

There is no (90, 139, 218275)-net in base 8, because

1 times m-reduction [i] would yield (90, 138, 218275)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 42311 268449 341715 000641 458689 214950 175666 844196 063588 776182 750276 847322 990707 017935 331726 412249 312529 136774 343521 839814 357916 > 8¹³⁸ [i]
