(153, 153+53, 1662)-Net over F₄ — Digital

Digital (153, 206, 1662)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(153, 153+53, 196397)-Net in Base 4 — Upper bound on s

There is no (153, 206, 196398)-net in base 4, because

1 times m-reduction [i] would yield (153, 205, 196398)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2644 320023 344984 865737 875475 250407 712408 004075 065768 751499 389692 433664 526145 158686 552233 155863 690913 287022 189355 831516 748780 > 4²⁰⁵ [i]
