COMMENTS
Conjecture: For all n, A209861(A054429(n)) = A054429(A209861(n)), i.e. A054429 acts as an homomorphism (automorphism) of the cyclic group generated by this permutation. This implies also a weaker conjecture given in A209860.
The scatterplot graph of the sequence has a nice texture and interesting pattern.
FORMULA
a(n) = A209640(A209642(n)).
