  We explicitly describe a noteworthy transcendental continued fraction in the
field of power series over Q, having irrationality measure equal to 3. This
continued fraction is a generating function of a particular sequence in the set
{1, 2}. The origin of this sequence, whose study was initiated in a recent
paper, is to be found in another continued fraction, in the field of power
series over $\mathbb{F}\_3$, which satisfies a simple algebraic equation of
degree 4, introduced thirty years ago by D. Robbins.
