(222−100, 222, 3018)-Net in Base 4 — Upper bound on s

There is no (122, 222, 3019)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 45 577308 658580 495484 478429 009789 240660 475374 614138 027393 149090 894683 827997 618732 030887 511839 572879 077679 039384 756344 612209 484433 156476 > 4²²² [i]
