(246−166, 246, 577)-Net in Base 4 — Upper bound on s

There is no (80, 246, 578)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13921 638965 021996 267552 407391 628124 994715 609909 209736 023353 782305 183233 217414 955145 596012 636014 548824 552068 440026 214570 191730 662995 841078 978741 464320 > 4²⁴⁶ [i]
