Digital (152, 231, 569)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(152, 231, 18203)-Net in Base 4 — Upper bound on s

There is no (152, 231, 18204)-net in base 4, because

1 times m-reduction [i] would yield (152, 230, 18204)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 981107 481703 633005 434172 634952 020572 987651 701940 509327 386934 725914 801062 367698 964358 523533 113784 469795 800626 910398 113877 637426 715547 547952 > 4²³⁰ [i]
