(104, 157, 427)-Net over F₄ — Digital

Digital (104, 157, 427)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(104, 157, 14384)-Net in Base 4 — Upper bound on s

There is no (104, 157, 14385)-net in base 4, because

1 times m-reduction [i] would yield (104, 156, 14385)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 8351 866058 189630 787651 461195 988965 310057 558755 706864 369904 800845 121760 023525 059005 602283 006384 > 4¹⁵⁶ [i]
