(150, 205, 1376)-Net over F₄ — Digital

Digital (150, 205, 1376)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(150, 205, 128857)-Net in Base 4 — Upper bound on s

There is no (150, 205, 128858)-net in base 4, because

1 times m-reduction [i] would yield (150, 204, 128858)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 661 150293 455402 029529 480103 685684 238330 188147 008367 832613 946517 228683 314886 041544 525990 202716 688111 406129 204587 916728 565808 > 4²⁰⁴ [i]
