(80, 80+136, 658)-Net in Base 4 — Upper bound on s

There is no (80, 216, 659)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12091 114897 304370 176682 956970 925566 345493 723378 443992 321397 584019 479279 358976 421571 753672 149270 292153 927942 010317 733574 815201 495000 > 4²¹⁶ [i]
