(50, 87, 1599)-Net over F₂₇ — Digital

Digital (50, 87, 1599)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(50, 87, 2003976)-Net in Base 27 — Upper bound on s

There is no (50, 87, 2003977)-net in base 27, because

1 times m-reduction [i] would yield (50, 86, 2003977)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 1251 077722 367951 124803 183934 671300 247642 966836 024064 470359 271321 021869 673332 894102 781378 844773 539653 454438 241131 629968 674665 > 27⁸⁶ [i]
