(108, 161, 479)-Net over F₄ — Digital

Digital (108, 161, 479)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(108, 161, 17809)-Net in Base 4 — Upper bound on s

There is no (108, 161, 17810)-net in base 4, because

1 times m-reduction [i] would yield (108, 160, 17810)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 138952 863813 619844 649688 143478 090176 416608 512191 767482 672818 901160 578875 877415 723098 553704 896960 > 4¹⁶⁰ [i]
