(120, 120+41, 1413)-Net over F₄ — Digital

Digital (120, 161, 1413)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(120, 120+41, 181395)-Net in Base 4 — Upper bound on s

There is no (120, 161, 181396)-net in base 4, because

1 times m-reduction [i] would yield (120, 160, 181396)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 136134 806232 593206 791682 132523 557451 821101 786324 905807 796353 086866 490012 563664 754699 518198 650416 > 4¹⁶⁰ [i]
