Gilbertâ€“VarÅ¡amov bound [i]

(135, 219, 7551)-Net in Base 4 — Upper bound on s

There is no (135, 219, 7552)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 712872 218620 235289 170615 741204 961413 637651 953406 021330 039372 482151 694080 753891 608417 066663 087752 631063 974744 076416 917569 943497 944525 > 4²¹⁹ [i]
