(28, 28+17, 2429)-Net over F₂₅ — Digital

Digital (28, 45, 2429)-net over F₂₅, using

Gilbertâ€“VarÅ¡amov bound [i]

(28, 28+17, 7658587)-Net in Base 25 — Upper bound on s

There is no (28, 45, 7658588)-net in base 25, because

1 times m-reduction [i] would yield (28, 44, 7658588)-net in base 25, but
- the generalized Rao bound for nets shows that 25^mÂ â‰¥ 32 311774 156846 846584 855381 041633 824703 783121 304715 705223 884545 > 25⁴⁴ [i]
