%N Smallest abundant number relatively prime to n.

%C If we require only non-deficient, all the 12's become 6's and the 56's become 28's, plus some other changes for large n (such as n = 3234846615 = 3*5*7*11*13*17*19*23*29, 16256 becomes 8128).

%Y Cf. A005101, A005231, A047802, A000396, A114809.
