(155−39, 155, 1449)-Net over F₄ — Digital

Digital (116, 155, 1449)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(155−39, 155, 200408)-Net in Base 4 — Upper bound on s

There is no (116, 155, 200409)-net in base 4, because

1 times m-reduction [i] would yield (116, 154, 200409)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 521 516082 640767 504931 366389 293718 643542 636869 052888 737622 685069 586982 502869 687308 855913 848872 > 4¹⁵⁴ [i]
