(91−70, 91, 2480)-Net in Base 25 — Upper bound on s

There is no (21, 91, 2481)-net in base 25, because

the generalized Rao bound for nets shows that 25^mÂ â‰¥ 16 503677 567372 177557 964422 419790 248540 407300 718896 461762 890551 451383 477389 717486 029348 889205 782888 882979 470712 695872 182376 612745 > 25⁹¹ [i]
