%U A077006 554400
%N A077006 Numbers n such that sigma(n)/n >= sigma(m)/m for all m <= n.
%e A077006 360360 is included in this sequence (but not in A004394) because its 
               abundancy (sigma(n)/n = 48/11) is the same as that of the previous 
               record holder (namely 332640). [From Gerard P. Michon (g.michon(AT)att.net),
