Properties

Appears in sequences

• Define an increasing sequence as follows. Given the first term called the seed (the seed need not have the property of the sequence.). Subsequent terms are defined as obtained by inserting/placing digits (at least one) in the previous term to obtain the smallest number with a given property. This is the growing prime sequence for the seed a(1) = 7.at n=5A068172
• Primes p such that p+2, n*(p+2)+6 and p*(p+2)+8 are also prime.at n=20A130735
• Concatenation of first 3 digits and last 3 digits of n-th Mersenne prime A000668(n).at n=14A138866
• a(n+1) is the smallest prime > a(n) such that the digits of a(n) are all (with multiplicity) contained in the digits of a(n+1), with a(1)=7.at n=23A242907
• Primes p such that p^3 is the concatenation of two k-digit primes where k is half the number of decimal digits in p^3.at n=21A248208
• Emirps p such that p+(sum of digits of p) and reverse(p)+(sum of digits of p) are emirps.at n=4A340843
• Prime numbersat n=9941
