OEIS Sequences

Lower prime of a difference of 20 between consecutive primes. A31938

Primes whose sum of digits is 8. A62343

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) = 2. A68167

Coefficients of monic irreducible polynomials over GF(4) listed in lexicographic order. A58948

Coefficients of monic primitive irreducible polynomials over GF(4) listed in lexicographic order. A58952

Least prime in A031938 (lesser of primes differing by 20) whose distance to the next 20-twin is 6·n. A52359

Decimal value of the bitmap of active segments in 7-segment display of the number n, variant 2 ("abcdefg" scheme: bits represent segments in clockwise order). A234692

Primes of the form 2·n² + 50·n + 23. A217496

Smallest number of each digital type. A266946

a(1) = 1; 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). A389824
