Properties

Appears in sequences

• Let f(m) = smallest composite number that takes m steps of "add prime factors to number" to reach a prime and g(m) be the prime that is reached. Sequence gives values of g(m), sorted and duplicates removed.at n=13A050767
• Smallest k such that (10^n+k, 10^n+k+2) and (10^(n+1)+k, 10^(n+1)+k+2) are two pairs of twin primes with k(n+1) > k(n).at n=12A224846
• Decimal representation of the x-axis, from the origin to the right edge, of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 433", based on the 5-celled von Neumann neighborhood.at n=16A282202
• Primes having only {0, 8, 9} as digits.at n=9A385772
• Primes having only {0, 5, 8, 9} as digits.at n=41A386081
• Prime numbersat n=8695
