(79, 215, 643)-Net in Base 4 — Upper bound on s

There is no (79, 215, 644)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2841 946814 884897 504412 671049 042244 616493 180723 370496 408909 961024 710453 700444 468593 765007 396533 254722 811723 526304 054658 525819 275584 > 4²¹⁵ [i]
