 A143744 The number of steps needed to generate the next largest juggler number. 0

 OFFSET 1,3 COMMENTS 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.

Smith, Juggler Sequence EXAMPLE 8 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.
