(15, 15+64, 8213)-Net in Base 81 — Upper bound on s

There is no (15, 79, 8214)-net in base 81, because

the generalized Rao bound for nets shows that 81^mÂ â‰¥ 5 906411 037388 410331 663536 997570 515717 150202 872832 198485 151499 785749 833455 364894 669744 764505 179843 722040 563559 775982 981204 479680 091430 995340 252504 099841 > 81⁷⁹ [i]
