(18, 18+66, 1966)-Net in Base 25 — Upper bound on s

There is no (18, 84, 1967)-net in base 25, because

the generalized Rao bound for nets shows that 25^mÂ â‰¥ 2689 186973 910175 159841 327598 555451 593823 449456 348637 155110 469588 993991 665795 258058 035612 952732 352023 333613 758632 060265 > 25⁸⁴ [i]
