(170−61, 170, 1226)-Net over F₈ — Digital

Digital (109, 170, 1226)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(170−61, 170, 210406)-Net in Base 8 — Upper bound on s

There is no (109, 170, 210407)-net in base 8, because

1 times m-reduction [i] would yield (109, 169, 210407)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 419 034535 690183 811134 117887 211713 225254 196003 750869 015380 566669 691980 129065 495648 938928 773188 333132 419230 641601 545041 332459 573541 180246 408514 150599 455020 > 8¹⁶⁹ [i]
