Antti Karttunen, Table of n, a(n) for n = 1..65537
Index entries for sequences related to binary expansion of n
a(n) = A004198(n, A032742(n)).
a(n) = n + A032742(n) - A318514(n) = (n+A032742(n)-A106409(n))/2.
(PARI)
A032742(n) = if(1==n, n, n/vecmin(factor(n)[, 1]));
A318515(n) = bitand(n, A032742(n));
