Gilbertâ€“VarÅ¡amov bound [i]

(181−59, 181, 820)-Net in Base 2 — Upper bound on s

There is no (122, 181, 821)-net in base 2, because

1 times m-reduction [i] would yield (122, 180, 821)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 1 579264 299320 425210 561782 292917 010644 409508 347026 380104 > 2¹⁸⁰ [i]
