Properties

Appears in sequences

• Primes p such that (p-1)/2 and (p-3)/4 are also prime.at n=32A066179
• Initial term in sequence of four consecutive primes separated by 3 consecutive differences each <=6 (i.e., when d=2,4 or 6) and forming d-pattern=[6, 6,2]; short d-string notation of pattern = [662].at n=18A078857
• Magnanimous primes: primes with the property that inserting a "+" in any place between two digits yields a sum which is prime.at n=47A089392
• Numbers k such that k^4 = x^3 + y^2 has an integer solution.at n=46A096741
• Primes p such that denominator of Sum_{k=1..p-1} 1/k^2 is a square and denominator Sum_{k=1..p-1} 1/k^3 is a cube and denominator Sum_{k=1..p-1} 1/k^4 is a fourth power.at n=16A127062
• Numbers such that the digital sums in bases 2, 3, 5 and 7 all are equal.at n=28A135127
• Primes of the form p=3*q+3*r+q*r where q and r are distinct primes and 2*p-3*q, 2*p-3*r and 2*p-q*r are also prime.at n=45A328822
• Primes which, when added to their reversals, produce palindromic primes.at n=34A342681
• Primes p such that, if b is the sum of digits of p, y = p mod b and x = (p-y)/b, then p-x*y, p+x*y, x+y and x-y are all prime.at n=42A342801
