A Symmetry Property of Christoffel Words
<|reference_start|>A Symmetry Property of Christoffel Words: Motivated by the theory of trapezoidal words, whose sequences of cardinality of factors by length are symmetric, we introduce a bivariate variant of this symmetry. We show that this symmetry characterizes Christoffel words, and establish other related results.<|reference_end|>
