Properties

Appears in sequences

• Fourth step in Goodstein sequences, i.e., g(6) if g(2)=n: write g(5)=A059934(n) in hereditary representation base 5, bump to base 6, then subtract 1 to produce g(6).at n=12A059935
• Primes which can be expressed as sum of distinct powers of 6.at n=13A077720
• Primes of the form k*6^m +1 where k is a Mersenne prime (A000668) and m is an integer.at n=7A185167
• a(n) = 7*6^n+1.at n=6A199321
