(25, 25+31, 11129)-Net in Base 16 — Upper bound on s

There is no (25, 56, 11130)-net in base 16, because

1 times m-reduction [i] would yield (25, 55, 11130)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 1 686462 139935 139432 092516 917714 713056 941718 953404 118311 485719 352376 > 16⁵⁵ [i]
