A finite sequence u = ala2 . up of some symbols is contained in another sequence c = h1b2.. b, if there is a subsequence b,,bi, b,, of u which can be identified, after an injective renaming of symbols, with u. We say that u = u1a2.. .up is k-regular if i -j > k whenever a, = a,, i > j. We denote fur

One class of Davenport-Schinzel sequences consists of finite sequences over n symbols without immediate repetitions and without any subsequence of the type abab. We present a bijective encoding of such sequences by rooted plane trees with distinguished nonleaves and we give a combinatorial proof of
