Ferrari %J Online Journal of Analytic Combinatorics %D 2011 %I University of Auckland %X A word is centrosymmetric if it is invariant under the reverse-complement map. In this paper, we give enumerative results on $k$-ary centrosymmetric words of length $n$ avoiding a pattern of length 3 with no repeated letters. %U http://analytic-combinatorics.org/index.php/ojac/article/view/39
