%N A036912 Indices of the left-to-right maxima in A057635.
%C A036912 A number m belongs to this sequence iff A057635(k)<A057635(m) for all 
               k<m.
%C A036912 Indices of records in A057635(n), the maximal m with phi(m)=n.
%C A036912 The Alekseyev link in A131883 establishes the following explicit relationship 
               between A131883, A036912 and A057635. Namely, for t belonging to 
               A036912, we have t=A131883(A057635(t)-1). In other words, A036912(n) 
               = A131883(A057635(A036912(n))-1) for all n.
