(168−57, 168, 1616)-Net over F₈ — Digital

Digital (111, 168, 1616)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(168−57, 168, 392802)-Net in Base 8 — Upper bound on s

There is no (111, 168, 392803)-net in base 8, because

1 times m-reduction [i] would yield (111, 167, 392803)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 6 546969 615203 156267 349017 068652 703765 299008 808875 533008 092788 025897 411148 610638 512506 616651 786208 368542 751985 495686 027005 587305 259574 158910 649423 688952 > 8¹⁶⁷ [i]
