(131−106, 131, 555)-Net in Base 9 — Upper bound on s

There is no (25, 131, 556)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 103292 048094 917318 455331 340029 580129 681262 253808 922095 789178 279350 163864 602759 194256 228409 715956 429043 945137 748998 056852 379617 > 9¹³¹ [i]
