(243−164, 243, 570)-Net in Base 4 — Upper bound on s

There is no (79, 243, 571)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 220 153516 866649 088488 999516 309302 640038 583587 775220 845262 262656 509820 691815 226291 120187 596727 363434 618432 571266 449598 886779 131765 424253 224058 806760 > 4²⁴³ [i]
