• Lonely (or isolated) primes: increasing distance to nearest prime.at n=9A023186
• Lonely (or isolated) primes: least prime of distance n from nearest prime (n = 1 or even).at n=15A023188
• a(n) = prime(100*n).at n=26A031921
• Prime islands: for n >= 2, a(n) = least prime whose adjacent primes are exactly 2n apart; a(1) = 3 by convention.at n=32A046931
• Lonely numbers: distance to closest prime sets a new record.at n=17A051650

• Primes p whose reciprocal has period (p-1)/10.at n=31A056215
• (Prime(n)+prime(n+1)+prime(n+2))/(n+1) is an integer; sequence gives prime(n).at n=7A072162
