Properties

Appears in sequences

• Primes with consecutive digits that differ exactly by 1.at n=22A048398
• Numbers k such that 70^k - 69^k is prime.at n=3A062636
• 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=36A084160
• Primes with minimal digit = 7.at n=28A106107
• Primes having only {7, 8, 9} as digits.at n=30A106110
• Primes with digit sum = 41.at n=3A106774
• Primes p such that q-p = 42, where q is the next prime after p.at n=11A134120
• Consecutive Pythagorean primes p = A002144(r) and q = A002144(r+1) such that q - p > log(p)^2. The number a(n) is the n-th value of p.at n=10A216924
• Number of partitions of n^2 into exactly 4 prime numbers.at n=41A243940
• Prime numbersat n=7746
