(66, 224, 450)-Net in Base 4 — Upper bound on s

There is no (66, 224, 451)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 731 356579 936880 519539 437217 249418 287705 638244 985732 756866 099626 075567 021802 935683 821300 691551 790797 574665 557525 467744 902086 873789 079552 > 4²²⁴ [i]
