(105, 105+61, 332)-Net over F₄ — Digital

Digital (105, 166, 332)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(105, 105+61, 8197)-Net in Base 4 — Upper bound on s

There is no (105, 166, 8198)-net in base 4, because

1 times m-reduction [i] would yield (105, 165, 8198)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2188 011630 392847 225144 532585 002819 185067 677891 769689 842615 581133 004999 290408 314541 796231 435513 589760 > 4¹⁶⁵ [i]
