The Lyndon factorization of a finite word w is its unique factorization as a non-increasing product of Lyndon words, i.e., $w = l_1\dots l_n$ where each $l_i$ is a Lyndon word and $l_1 \geq\dots\geq l_n$. ----------------------------------------------------------------------------- References: [1] [[wikipedia:Lyndon word]] [2] Duval, J.-P.
