(172−65, 172, 947)-Net over F₈ — Digital

Digital (107, 172, 947)-net over F₈, using

Gilbertâ€“VarÅ¡amov bound [i]

(172−65, 172, 122348)-Net in Base 8 — Upper bound on s

There is no (107, 172, 122349)-net in base 8, because

1 times m-reduction [i] would yield (107, 171, 122349)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 26819 994387 330589 780983 568601 709451 620688 458435 993047 520752 148362 123822 391936 794722 756971 330779 273300 003411 001197 104663 508859 795884 305478 138009 154046 401903 > 8¹⁷¹ [i]
