%N Number of partitions of n into distinct Catalan numbers, cf. A000108.
%C a(n) <= 1;
%C a(A000108(n)) = 1; a(A141351(n)) = 1; a(A014138(n)) = 1.
%C A197433 gives all such numbers k that a(k) = 1, in other words, this is the characteristic function of A197433, and all three sequences mentioned above are its subsequences. - _Antti Karttunen_, Jun 25 2014

%F a(n) = f(n,1,1) with f(m,k,c) = if c>m then 0^m else f(m-c,k+1,c') + f(m,k+1,c') where c'=2*c*(2*k+1)/(k+2).
%e 56 = 42+14 = A000108(5)+A000108(4), all other sums of distinct Catalan numbers are not equal 56, therefore a(56)=1.

%Y When right-shifted (prepended with 1) this sequence is the first differences of A244230.
%Y Cf. A033552, A197433, A161227 - A161239.
