 OFFSET 1,2 COMMENTS A permutation of the natural numbers. The natural density of positive integers m such that A003557(m) = a(n) equals 6/(A181798(n)*Pi^2). If m is coprime to 6, 3m and 4m appear in A003557 equally often. LINKS Table of n, a(n) for n=1..70. Wikipedia, Natural density FORMULA The natural density of positive integers m such that A003557(m) = n equals 6/(A181797(n)*Pi^2). A181797(n) = n*A048250(n).
