OEIS Sequences

Absolute discriminants of complex quadratic fields with 3-class group of elementary abelian type (3,3) of rank 2. A242863

Initial term in sequence of four consecutive primes whose consecutive differences have d-pattern = [6, 4, 6]; short d-string notation for pattern = [646]. A78856

Absolute discriminants of complex quadratic fields with 3-class group of type (3,3), 3-principalization type (4443), IPAD [(3,3,3)³, (3,9)], and Hilbert 3-class field tower of unknown length at least 3. A242873

Primes that are the average of the members of emirp pairs. A178581

a(n) is the first term that can be reduced in n steps via repeated interpretation of a(n) as a base b+1 number where b is the largest digit of a(n), such that b is always 7 so that each interpretation is base 8. Terms already fully reduced (i.e., single digits) are excluded. A141841

Primes p such that 8·p²-2·p-1 divides Fibonacci(p). A159231

Primes p such that the differences between the 5 consecutive primes starting with p are (6,4,6,6). A78964

Primes that are the average of the members of more than one emirp pair. A178587

Smallest prime that is the average of the members of exactly n emirp pairs. A178589

Primes p such that 2·p² + 3 and 2·p² + 5 are also primes. A247197
