(153−53, 153, 380)-Net over F₄ — Digital

Digital (100, 153, 380)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(153−53, 153, 11617)-Net in Base 4 — Upper bound on s

There is no (100, 153, 11618)-net in base 4, because

1 times m-reduction [i] would yield (100, 152, 11618)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 32 620325 497682 775402 963432 504347 781291 277231 139174 805299 985516 413206 443523 141484 567434 330480 > 4¹⁵² [i]
