(252−120, 252, 2562)-Net in Base 4 — Upper bound on s

There is no (132, 252, 2563)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 53 325890 422718 644847 181108 044356 149970 178751 191607 470257 595275 576680 716895 915621 052195 520033 893298 086343 301961 931694 571590 622198 298991 698421 676191 217024 > 4²⁵² [i]
