OEIS Sequences

Prime islands: for n >= 2, a(n) = least prime whose adjacent primes are exactly 2n apart; a(1) = 3 by convention. A46931

T(n,k)=Majority value maps: number of nXk binary arrays indicating the locations of corresponding elements equal to at least half of their horizontal and antidiagonal neighbors in a random 0..1 nXk array. A220386

Primes p such that q-p = 40, where q is the next prime after p. A126721

Numbers k such that k concatenated with k+1 gives the product of two numbers which differ by 7. A116167

Numbers k such that k concatenated with k+7 gives the product of two numbers which differ by 5. A116207

Numbers k such that k concatenated with k-7 gives the product of two numbers which differ by 9. A116114

G.f. satisfies: A(x) = x*(1 - x²*A(x)²)/(1 + x²*A(x)²)². A278745

Primes P where the distance to the nearest prime is greater than 2·log(P). A330426

Fifth term of weak prime sextet: p(m-3)-p(m-4) < p(m-2)-p(m-3) < p(m-1)-p(m-2) < p(m)-p(m-1) < p(m+1)-p(m). A54832

"Lonely primes": those primes that are locally maximally isolated from the nearest other primes. The differences between each lonely prime and the immediately preceding prime and following primes are both greater than the corresponding differences for all lonely primes earlier in the sequence.
