(217−62, 217, 67790)-Net in Base 4 — Upper bound on s

There is no (155, 217, 67791)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 44371 065207 487624 826727 481454 074592 356723 563729 900059 375924 263929 805468 886193 486533 077010 825349 282295 982757 772707 832300 887753 062224 > 4²¹⁷ [i]
