%N Triangle read by rows in which row n lists the compositions of n ordered first by decreasing length and then reverse-lexicographically.
%C The ordering of compositions in each row is consistent with the reverse-Mathematica ordering of expressions (cf. A124734).
%C Length of k-th composition is A124748(k-1)+1. - _Andrey Zabolotskiy_, Dec 20 2017
