Appears in sequences
- Let m = A002445(n); then a(n) = largest member of A001359 (the lesser twin primes sequence) <= m.at n=29A156053
- Lesser of twin-bin primes: primes p such that p+2, x and y are primes, where x is concatenation of binary representations of p and p+2, and y is concatenation of binary representations of p+2 and p: x = p * 2^A070939(p+2) + p+2, y = (p+2) * 2^A070939(p) + p.at n=8A232239
- Numbers n such that prime(n) + {1, 2, 3, 4, 5, 6} are all products of the same number of primes (not necessarily all distinct).at n=14A255202
