(20, 20+39, 2495)-Net in Base 16 — Upper bound on s

There is no (20, 59, 2496)-net in base 16, because

1 times m-reduction [i] would yield (20, 58, 2496)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 6952 194999 210084 692621 348958 283895 256770 611036 611251 436540 841048 364461 > 16⁵⁸ [i]
