(80, 80+31, 693)-Net over F₄ — Digital

Digital (80, 111, 693)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(80, 80+31, 55674)-Net in Base 4 — Upper bound on s

There is no (80, 111, 55675)-net in base 4, because

1 times m-reduction [i] would yield (80, 110, 55675)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1 685102 883141 356548 842219 827267 675654 040739 187086 323925 546956 752416 > 4¹¹⁰ [i]
