Abstract

It is shown that $c = -29/16$ is the unique rational number with smallest denominator, and the unique rational number of smallest numerator, for which the map $f(x) = x^2 + c$ has a rational cycle with period $3$. Several arithmetic conditions on the set of all such rational numbers $c$ are proved.
