(103, 160, 358)-Net over F₄ — Digital

Digital (103, 160, 358)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(103, 160, 9856)-Net in Base 4 — Upper bound on s

There is no (103, 160, 9857)-net in base 4, because

1 times m-reduction [i] would yield (103, 159, 9857)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 534833 572739 915221 935272 089870 840230 688123 706666 048499 081799 332223 957835 920307 719012 776685 410208 > 4¹⁵⁹ [i]
