(113−25, 113, 733603)-Net in Base 4 — Upper bound on s
There is no (88, 113, 733604)-net in base 4, because
- 1 times m-reduction [i] would yield (88, 112, 733604)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 26 960371 235495 445982 380775 666540 618638 676461 337839 836725 273108 294840 > 4112 [i]
