%S A143745 1,2,36,140,52214,24906114455136,202924588924125339424550328
%N A143745 The next largest juggler number.
%C A143745 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.
%C A143745 I have a b-file for this sequence for n=1,...,19 (all known values), 
               but some a(n) values are much larger than 1000 digits.

               p. 233.

%e A143745 24906114455136 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.
%Y A143745 Cf. A007320, A094670, A094679, A094683, A094684, A095908.
