Properties

Appears in sequences

• Numbers k such that (15^k - 1)/14 is prime.at n=7A006033
• Consider the version of the Collatz or 3x+1 problem where x -> x/2 if x is even, x -> (3x+1)/2 if x is odd. Define the stopping time of x to be the number of steps needed to reach 1. Sequence gives the number of integers x with stopping time n.at n=41A060322

• Primes having only {0, 8, 9} as digits.at n=8A385772
• Primes having only {0, 5, 8, 9} as digits.at n=39A386081
