 A143745 The next largest juggler number. 1

 OFFSET 1,2 COMMENTS The juggler sequence: begin with a starting value x and if x is even, x <- floor(sqrt(x)) and if x is odd, x <- floor(sqrt(x^3)) and repeat until x = 1, save the starting value, max x and the number of steps needed to reach it. 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. REFERENCES C.

Smith, Juggler Sequence Eric Weisstein's World of Mathematics, Juggler Sequence EXAMPLE 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. CROSSREFS Cf. A007320, A094670, A094679, A094683, A094684, A095908.
