Appears in sequences
- If a, b in sequence, so is ab+8.at n=39A009331
- a(n) = A027113(n, n+4).at n=8A027117
- a(n) = A027113(n, 2n-8).at n=8A027126
- Consider the trajectory of n under the iteration of a map which sends x to 3x - sigma(x) if this is >= 0; otherwise the iteration stops. The sequence gives values of n which eventually reach 0.at n=18A037159
- Positive numbers having the same set of digits in base 4 and base 10.at n=39A037428
- Becomes prime or 4 after exactly 8 iterations of f(x) = sum of prime factors of x.at n=39A048130
- McKay-Thompson series of class 32A for Monster.at n=36A058629
- Period of the continued fraction for sqrt(2^n-1).at n=31A059866
- Multiples of 8 with digit sum 8.at n=27A069543
- Each digit of a(n) appears in a(n+1) and a(n+1) > a(n) is minimal.at n=40A107411
- Quaternary emirpimes.at n=25A114015
- A123896 sorted and duplicates removed.at n=34A123902
