COMMENTS
The defining inequality {-m*r} > {n*r} is equivalent to {m*r} + {n*r} < 1. Are all a(n) in A084068? Are all a(n) denominators of intermediate convergents to sqrt(2)?
EXAMPLE
a(3)=2 because {-m*r} < {3*r} = 0.2426... for m=1 whereas
{-2*r} = 0.1715..., so that 2 is the least m for which
{-m*r} < {3*r}.
