(79, 79+142, 623)-Net in Base 4 — Upper bound on s

There is no (79, 221, 624)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 338330 827235 260973 998259 835068 344957 744586 710712 759936 263823 648487 149272 309139 508698 463903 758341 025394 998563 058733 501922 432197 738763 > 4²²¹ [i]
