(112, 112+57, 1676)-Net over F₈ — Digital

Digital (112, 169, 1676)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(112, 112+57, 423086)-Net in Base 8 — Upper bound on s

There is no (112, 169, 423087)-net in base 8, because

1 times m-reduction [i] would yield (112, 168, 423087)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 52 376724 341475 344488 368497 569712 003933 078890 756490 558890 344305 840441 589950 563495 697863 973809 763145 276205 147435 275225 964195 401782 915027 420015 876050 802054 > 8¹⁶⁸ [i]
