(244−124, 244, 843)-Net in Base 3 — Upper bound on s

There is no (120, 244, 844)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 277 335999 546174 978077 643268 884711 624406 216087 733452 701011 455527 952877 442368 425052 016008 613383 469944 489497 754107 198473 > 3²⁴⁴ [i]
