(21, 21+31, 18165)-Net in Base 27 — Upper bound on s
There is no (21, 52, 18166)-net in base 27, because
- 1 times m-reduction [i] would yield (21, 51, 18166)-net in base 27, but
- the generalized Rao bound for nets shows that 27m ≥ 9 993245 230045 940019 992198 640664 061746 359834 300022 182410 256399 939216 351513 > 2751 [i]
