(108, 108+152, 1052)-Net in Base 4 — Upper bound on s

There is no (108, 260, 1053)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 668496 986078 113570 084759 701643 029829 593183 598010 612913 376364 350489 842523 112656 652604 591741 106741 443344 169259 200514 796112 604116 185431 326756 386426 673136 589200 > 4²⁶⁰ [i]
