(237−128, 237, 1343)-Net in Base 4 — Upper bound on s

There is no (109, 237, 1344)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 50897 275474 351495 250298 549013 235001 336069 835940 803989 891391 268711 744281 686763 814495 775143 304476 576599 237178 262820 207562 329273 719110 667541 556020 > 4²³⁷ [i]
