Digital (130, 214, 330)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(130, 130+84, 6397)-Net in Base 4 — Upper bound on s

There is no (130, 214, 6398)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 696 891824 388482 247156 799768 021832 384583 451426 552698 678368 584488 232153 696959 071703 755176 828983 856969 664472 649156 703097 954717 620122 > 4²¹⁴ [i]
