Gilbertâ€“VarÅ¡amov bound [i]

(148, 148+89, 647)-Net in Base 2 — Upper bound on s

There is no (148, 237, 648)-net in base 2, because

1 times m-reduction [i] would yield (148, 236, 648)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 113276 258720 827476 007225 595549 257874 880906 639084 422840 444255 372206 266928 > 2²³⁶ [i]
