(228−152, 228, 560)-Net in Base 4 — Upper bound on s

There is no (76, 228, 561)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 194522 520018 567347 216918 163309 777562 404751 857381 205308 666396 996908 472411 742897 215737 111617 257384 190024 361947 297681 839680 784965 046889 002400 > 4²²⁸ [i]
