 OFFSET 1,4 COMMENTS The ordering of compositions in each row is consistent with the reverse-Mathematica ordering of expressions (cf. A124734). Length of k-th composition is A124748(k-1)+1. - Andrey Zabolotskiy, Dec 20 2017 LINKS EXAMPLE Triangle of compositions begins: (1), (11),(2), (111),(21),(12),(3), (1111),(211),(121),(112),(31),(22),(13),(4), (11111),(2111),(1211),(1121),(1112),(311),(221),(212),(131),(122),(113),(41),(32),(23),(14),(5).
