(98, 131, 1259)-Net over F₄ — Digital

Digital (98, 131, 1259)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(98, 131, 176653)-Net in Base 4 — Upper bound on s

There is no (98, 131, 176654)-net in base 4, because

1 times m-reduction [i] would yield (98, 130, 176654)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1 852681 909971 848428 374872 633657 557119 804569 962446 755178 161584 205769 568874 278432 > 4¹³⁰ [i]
