Gilbertâ€“VarÅ¡amov bound [i]

(244−92, 244, 9330)-Net in Base 4 — Upper bound on s

There is no (152, 244, 9331)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 802 448458 379992 376051 703508 409982 340165 227451 801714 965776 688913 248955 170643 466560 268894 870274 387313 862132 118104 176696 282214 948917 563397 122038 405908 > 4²⁴⁴ [i]
