(105, 105+116, 1425)-Net in Base 4 — Upper bound on s

There is no (105, 221, 1426)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 11 531643 286342 720580 291699 073433 685551 303541 417407 395173 790320 387336 260960 904722 085261 553140 118930 446965 041154 943631 601078 870820 538688 > 4²²¹ [i]
