Digital (54, 82, 247)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(54, 54+28, 6760)-Net in Base 4 — Upper bound on s

There is no (54, 82, 6761)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 23 413681 662312 277730 759688 679299 946249 972077 255568 > 4⁸² [i]
