(138−49, 138, 1081)-Net over F₈ — Digital

Digital (89, 138, 1081)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(138−49, 138, 200157)-Net in Base 8 — Upper bound on s

There is no (89, 138, 200158)-net in base 8, because

1 times m-reduction [i] would yield (89, 137, 200158)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 5289 023603 278799 733143 590430 041225 004971 682632 625220 931819 659054 997546 268867 742156 495347 162075 052601 806278 911219 111142 903623 > 8¹³⁷ [i]
