(74, 216, 560)-Net in Base 4 — Upper bound on s

There is no (74, 216, 561)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12251 029944 051724 963599 527538 453551 294735 560184 354730 779953 241201 521220 033689 817840 073135 416269 199725 027821 897246 630699 460291 011712 > 4²¹⁶ [i]
