Digital (126, 208, 317)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(208−82, 208, 6063)-Net in Base 4 — Upper bound on s

There is no (126, 208, 6064)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 169451 705538 069766 421138 379163 273384 380954 995385 500605 279220 879112 840630 911983 398677 303173 619467 805695 307018 391203 145449 192935 > 4²⁰⁸ [i]
