Digital (102, 157, 373)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(102, 102+55, 10939)-Net in Base 4 — Upper bound on s

There is no (102, 157, 10940)-net in base 4, because

1 times m-reduction [i] would yield (102, 156, 10940)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 8361 755448 261490 574382 653543 157653 340447 410790 148151 068567 998738 788902 037159 596580 227301 708125 > 4¹⁵⁶ [i]
