• Primes of the form 16*k-1 such that 4*k-1 and 8*k-1 are also primes.at n=26A101793
• Primes p with pi(p), pi(2*p), pi(3*p) and pi(4*p) all prime, where pi(x) denotes the number of primes not exceeding x.at n=1A240604
• Numbers m such that Conv(b,m) = b has a unique nontrivial solution (b = 0 and b = 1 are considered trivial solutions). Here, Conv(b,m) denotes the limit of b^^t (mod m) as t goes to infinity.at n=30A347561
• Primes such that the next 10 prime gaps are all distinct.at n=16A372550
