(150, 233, 498)-Net over F₄ — Digital

Digital (150, 233, 498)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(150, 233, 13693)-Net in Base 4 — Upper bound on s

There is no (150, 233, 13694)-net in base 4, because

1 times m-reduction [i] would yield (150, 232, 13694)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 47 749326 951988 385041 538180 532086 511652 918379 805468 543779 385001 169730 022125 512239 847653 783141 099698 107799 011545 052539 141649 431301 299244 019475 > 4²³² [i]
