Digital (124, 204, 318)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(204−80, 204, 6149)-Net in Base 4 — Upper bound on s

There is no (124, 204, 6150)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 661 484125 139952 927902 127846 353788 195598 204410 301386 538866 270475 688287 559901 976721 286066 724883 938337 524266 206815 629937 238784 > 4²⁰⁴ [i]
