(26, 51, 318749)-Net in Base 32 — Upper bound on s
There is no (26, 51, 318750)-net in base 32, because
- 1 times m-reduction [i] would yield (26, 50, 318750)-net in base 32, but
- the generalized Rao bound for nets shows that 32m ≥ 1809 263973 196108 765136 441184 125608 617993 636938 433250 433853 670008 462856 718751 > 3250 [i]
