We (potentially) run into trouble where n/sqrt(3) falls just short of an
integer. Using the continued fraction of sqrt(3) I'd check 5, 19, 71, 265,
... (where each term is 4 times the previous minus the one before that). Up
to 15,000 digits these hold, so it seems likely that this is true. Maybe
some effective form of Roth's theorem can be used to prove it.
