(137−49, 137, 1036)-Net over F₈ — Digital

Digital (88, 137, 1036)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(137−49, 137, 183543)-Net in Base 8 — Upper bound on s

There is no (88, 137, 183544)-net in base 8, because

1 times m-reduction [i] would yield (88, 136, 183544)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 661 088506 009581 518870 290487 360397 731201 791306 687557 837393 914142 933512 255942 082838 152602 089282 610231 975972 012689 908920 330044 > 8¹³⁶ [i]
