Properties

Appears in sequences

• Define an increasing sequence as follows. Given the first term, called the seed (which need not share the property of the remaining terms), subsequent terms are obtained by inserting at least one digit in the previous term so as to obtain the smallest number with the specified property. This is the prime sequence with the seed a(1) = 1.at n=6A068166
• 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) = 3.at n=6A068168
• Naughty primes: primes in which the number of zeros is greater than the number of all other digits.at n=29A164968
• Palindromic primes in the sense of A007500 with digits '0', '1' and '3' only.at n=39A199303
• Primes formed by concatenating k, k and 3 for k >= 1.at n=24A210512
• SanD primes with d = 14: p and p+d are both prime and digit sum A007953(p*(p+d)) = d.at n=18A307471
• a(1) = 2; for n > 1, a(n) is the smallest unused prime number that can be created by either removing or adding a single digit anywhere in the value of a(n-1).at n=12A389825
