(32, 32+31, 203742)-Net in Base 27 — Upper bound on s
There is no (32, 63, 203743)-net in base 27, because
- 1 times m-reduction [i] would yield (32, 62, 203743)-net in base 27, but
- the generalized Rao bound for nets shows that 27m ≥ 55537 114693 313536 408093 980998 798660 214201 692815 969999 638391 645387 946578 404897 639692 634363 > 2762 [i]
