(252−134, 252, 1525)-Net in Base 4 — Upper bound on s

There is no (118, 252, 1526)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 53 257108 749988 934964 916406 458861 768424 527017 895942 233159 469625 103048 753810 827607 869364 377495 951863 697090 151830 308244 693995 830133 375174 054646 341521 231550 > 4²⁵² [i]
