Properties

Appears in sequences

• Primes that are palindromic in base 13.at n=33A029980
• Least prime in A001359 (lesser of twin primes) such that the distance (A053319) to the next twin is 6*n.at n=33A052350
• Primes p_n such that n*p_n is a palindrome.at n=5A084121
• Primes p such that 2^j+p^j are primes for j=0,1,4,32.at n=3A094489
• n times pi(n) is a palindrome, where pi(n) = PrimePi(n) = A000720(n).at n=33A116054
• Primes of the form 2^x+2*x+y+2^y, with x and y integers of any sign.at n=36A162575
• a(1) = 3. For n > 1, Ulam's spiral is started with a(n-1), and the primes p on the NE spoke are considered. a(n) is the minimal p that is the lesser of a twin prime pair.at n=41A163586

• Primes p such that p+2, 3*p+2 and 3*p+8 are also primes.at n=20A278138
• Number of maximal subsets of {1..n} containing no sums or products of distinct elements.at n=33A326025
