Appears in sequences

• In the '3x+1' problem, these values for the starting value set new records for number of steps to reach 1.at n=40A033958
• Record n for the sequence A006666(n)/log(n), for n > 1; i.e., the n at which the number of steps to 1 for the halving-Collatz iteration divided by log(n) sets a new maximum.at n=8A123481
• Numbers n such that the ratio of tripling steps to halving steps in the Collatz (3x+1) trajectory of n is greater than all previous ratios.at n=8A248037
• Inputs n that yield a record-breaking value of A008908(n)/(log_2(n)+1) for the Collatz conjecture.at n=13A339614
• Composite numbers k such that A006577(k) sets a new record.at n=41A346591
