(16, 16+28, 878351)-Net in Base 256 — Upper bound on s

There is no (16, 44, 878352)-net in base 256, because

the generalized Rao bound for nets shows that 256^mÂ â‰¥ 9174 023987 052186 943367 304007 285817 445840 353531 308753 536314 083964 074386 135823 054356 166739 266104 795370 828591 > 256⁴⁴ [i]
