Properties

Appears in sequences

• The 6-tuples (d1,d2,d3,d4,d5,d6) with elements in {2,4,6} are listed in lexicographic order; for each 6-tuple, this sequence lists the smallest prime p >= 7 such that the differences between the 7 consecutive primes starting with p are (d1,d2,d3,d4,d5,d6), if such a prime exists.at n=7A078874
• Sorted version of A078874.at n=36A078875
• Primes p such that the differences between the 5 consecutive primes starting with p are (2,6,4,6).at n=19A078949
• a(1) = 7 then the smallest number such that the forward as well as the reverse n-th partial concatenation is a prime for n>1. (Reverse concatenation is taken term-wise and not digit-wise).at n=41A083994
• Number of length n+2 0..7 arrays with no three unequal elements in a row and no three equal elements in a row and new values 0..7 introduced in 0..7 order.at n=13A243726
• Primes of the form p*q+r*s+t*u, where p,q,r,s,t,u are consecutive primes.at n=6A340464
• Primes of the form prime(i)*prime(i+1)+prime(i+2)*prime(i+3)+...+prime(k-1)*prime(k).at n=26A340465
• Primes p such that p + 2, p + 8, p + 12, p + 18 and p + 20 are also primes.at n=7A383393
