(21, 21+58, 3111)-Net in Base 25 — Upper bound on s

There is no (21, 79, 3112)-net in base 25, because

the generalized Rao bound for nets shows that 25^mÂ â‰¥ 274 831885 410787 453130 942089 913414 907525 054742 468161 813324 304887 708455 403686 688344 743692 243070 474491 865184 819905 > 25⁷⁹ [i]
