%N A143742 Starting values that produce a larger juggler number than smaller starting 
               values.
%C A143742 The juggler sequence: begin with a starting value x and if x is even, 
               x <- [sqrt(x)] and if x is odd, x <- [sqrt(x^3)] and repeat until 
               x = 1, save the starting value, max x and the number of steps needed 
               to reach it.

%e A143742 37 is in the sequence because starting at 37 the juggler sequences maxes 
               out at 24906114455136, a 14 digit number, after 8 steps. This is 
               the largest juggler number found for starting values less than or 
               equal to 37.
