%N Sorted list of largest values in the quintuple (a,b,c,d,e) satisfying a^2 + b^2 + c^2 + d^2 + e^2 = a*b*c*d*e.

%e a(1)=4 since (4, 3, 3, 1, 1) is a solution of a^2 + b^2 + c^2 + d^2 + e^2 = a*b*c*d*e.

%e a(2)=5 since (5, 3, 3, 1, 1) is a solution.

%e a(3)=9 since (9, 4, 3, 1, 1) is a solution.
