(215, 215+44, 23828)-Net over F₄ — Digital

Digital (215, 259, 23828)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(215, 215+44, large)-Net in Base 4 — Upper bound on s

There is no (215, 259, large)-net in base 4, because

42 times m-reduction [i] would yield (215, 217, large)-net in base 4, but
- mutually orthogonal hypercube bound [i]
