(27, 27+54, 72559)-Net in Base 81 — Upper bound on s

There is no (27, 81, 72560)-net in base 81, because

the generalized Rao bound for nets shows that 81^mÂ â‰¥ 38674 826012 667483 929510 120999 655362 490606 199138 220244 061046 618419 289521 983197 505119 211780 397068 222795 262046 503054 096654 216706 837154 480946 353817 682659 641601 > 81⁸¹ [i]
