(90, 90+146, 419)-Net in Base 3 — Upper bound on s

There is no (90, 236, 420)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 40023 327586 427420 601023 818692 389102 215040 878033 063915 091843 824324 938073 694846 696766 750348 266613 447055 352993 615433 > 3²³⁶ [i]
