(152, 152+55, 1447)-Net over F₄ — Digital

Digital (152, 207, 1447)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(152, 152+55, 142795)-Net in Base 4 — Upper bound on s

There is no (152, 207, 142796)-net in base 4, because

1 times m-reduction [i] would yield (152, 206, 142796)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10578 657298 391767 410825 473022 644875 063554 742356 476141 372023 391496 270023 586854 716244 545930 260004 785354 959021 504126 526821 773252 > 4²⁰⁶ [i]
