(20, 20+31, 4411)-Net in Base 16 — Upper bound on s

There is no (20, 51, 4412)-net in base 16, because

1 times m-reduction [i] would yield (20, 50, 4412)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 1 607672 991322 907972 144387 974544 982085 171065 886269 218201 481076 > 16⁵⁰ [i]
