(246−138, 246, 600)-Net in Base 3 — Upper bound on s

There is no (108, 246, 601)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2454 967090 175407 154495 408316 582403 139947 668541 548636 231273 041234 801180 523538 716714 412221 580977 597153 598142 987335 462947 > 3²⁴⁶ [i]
