• In the '3x+1' problem, primes which as starting values set new records for number of steps to reach 1, where a step means either 'divide by two' or 'triple plus one and then divide by two'.at n=40A244638
• 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=10A248037
• Inputs n that yield a record-breaking value of A008908(n)/(log_2(n)+1) for the Collatz conjecture.at n=16A339614
• Prime numbersat n=390343
