%N A132597 Let S be the concatenation of natural numbers in ternary representation: 
               a(n) = position of first occurrence of n in S, then this occurrence 
               in S is replaced by a(n) in ternary.
%C A132597 A132598(n) = smallest m such that a(m) = n;
%C A132597 A132599 and A132600 give record values and where they occur;
%C A132597 XT00005 gives numbers m such that a(m) = m;
%C A132597 XT00006 gives positions m such that a(m)=a(m-1).
