  - an extension C_e(24) of the primitive narrow-sense BCH-code C(I) with length 4095Â = 8⁴âˆ’1, defining interval IÂ =Â [1,24], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 25 [i]

(60, 60+25, 1584496)-Net in Base 8 — Upper bound on s

There is no (60, 85, 1584497)-net in base 8, because

1 times m-reduction [i] would yield (60, 84, 1584497)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 7237 028775 322376 165100 365498 501625 736421 733329 678642 869492 625440 265343 226516 > 8⁸⁴ [i]
