(20, 61, 2256)-Net in Base 16 — Upper bound on s

There is no (20, 61, 2257)-net in base 16, because

1 times m-reduction [i] would yield (20, 60, 2257)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 1 769589 059160 905811 463889 397194 976013 630989 805687 171268 918248 924696 560976 > 16⁶⁰ [i]
