An asymptotically optimal sorting algorithm that uses Θ(n(log n+k)) component comparisons to lexicographically sort the set of n k-tuples is presented. This sorting algorithm builds the static data structure - the so called optimal lexicographic search tree - in which it is possible to perform member searching for an unknown k-tuple in at most [(log2(n+1)]+k−1 comparisons. The number of comparisons used by this search algorithm is optimal.
