(108, 258, 1067)-Net in Base 4 — Upper bound on s

There is no (108, 258, 1068)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 215744 585977 936796 703417 180355 531006 333556 827329 513713 045430 446990 070907 396602 530468 880192 144845 399322 460479 444657 998579 152947 511492 885781 916851 179068 891760 > 4²⁵⁸ [i]
