(131−108, 131, 508)-Net in Base 9 — Upper bound on s

There is no (23, 131, 509)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 105961 534124 375581 803032 696806 890819 349777 313611 746784 866904 913956 312924 608825 478707 050897 006517 143943 491232 376379 400129 152049 > 9¹³¹ [i]
