Properties

Appears in sequences

• First occurrence prime gaps of the primes in sequence A002313 (Real primes with corresponding complex primes). a(0) = 2 with length of gap 3. For n>0 the size of the gap in the sequence is 4n, a(n) is the starting prime of the gap.at n=20A084160
• Reverse digits of largest Chen primes, append to sequence if result is larger Chen prime then previous one with reverse digits.at n=18A118496
• Primes where the first digit equals the sum of all the other digits.at n=50A156307
• Primes of the form 1000*k + 1.at n=16A156655
• Primes dividing repunits R(10^n) for some n.at n=38A178070
• Smallest prime factor of (n^n)^2 + 1 having the form k*n+1.at n=18A208399
• Prime factors (counting multiplicity) of 10^10^10^10^2 - 1.at n=40A278835
• Lesser of twin happy primes.at n=8A387240
