(20, 108, 1917)-Net in Base 25 — Upper bound on s

There is no (20, 108, 1918)-net in base 25, because

the generalized Rao bound for nets shows that 25^mÂ â‰¥ 9 560592 280967 643939 088090 091442 275943 099361 771349 532279 166813 800591 726036 785612 276380 759218 050820 257195 838222 596336 561133 315147 101755 072055 438550 210625 > 25¹⁰⁸ [i]
