    - K_1,2 from the tower of function fields by Niederreiter and Xing based on the tower by GarcÃa and Stichtenoth over F₂₅₆ [i]

(25, 25+36, 4293848)-Net in Base 256 — Upper bound on s

There is no (25, 61, 4293849)-net in base 256, because

the generalized Rao bound for nets shows that 256^mÂ â‰¥ 799 170878 295720 556459 165125 550027 397439 879907 933936 889044 654285 711801 804062 098601 986716 940674 990968 732050 758420 438540 699101 545758 410365 837622 610036 > 256⁶¹ [i]
