%C A038752 From _Georg Fischer_, Feb 11 2021: (Start)
%C A038752 An algorithm may try to estimate terms a(n) = m for m = 0, 1, 2, ... as follows:
%C A038752 - for m <= n the partition property must be satisfied,
%C A038752 - m = n+1 must be accepted as the "earliest" new member,
%C A038752 - for any m > n (estimated or computed), a(m) can immediately be computed by a(m)=a(a(n))=p(n). (End)
