(55, 55+53, 746)-Net over F₂₇ — Digital

Digital (55, 108, 746)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(55, 55+53, 315437)-Net in Base 27 — Upper bound on s

There is no (55, 108, 315438)-net in base 27, because

1 times m-reduction [i] would yield (55, 107, 315438)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 1431 975323 377570 458064 850384 120892 863593 110932 825866 412987 961321 022223 899808 020199 125574 797239 091881 426934 288351 738450 568833 250665 033354 228996 179348 311181 > 27¹⁰⁷ [i]
