%N Fixed points of A069787: Numbers n such that A069787(n) = n.
%C Although in principle a list, the indexing of this sequence starts from zero, as 0 is always fixed by all Catalan bijections (permutations induced by bijective operations performed on A014486), so it is a trivial case, which can be skipped by considering only values from a(n>=1) onward.
%C Sequence gives also the positions of all zeros in A243492.
