%N Triangle read by rows in which row n lists the F-ranks of all compositions of n in nondecreasing order, n >= 0.
%C Also row n lists the L-ranks of all compositions of n in nondecreasing order. For the definition of both F-rank and L-rank of a composition see A228820.
%C Row sums is always 0.
%C Row lengths is A000079.
%C Column 1 is -1*A001477(n).
%C Right border gives A000225.
%C Row sums of nonnegative terms give A228820.
