OEIS Sequences

Semiprimes which are products of two primes each with half the number of digits, and which when split in the middle gives two primes; no leading zeros. A243749

a(n) = b(n) + d(n), where b(n) = (n-th Lucas number > 3) and d(n) = (n-th number that is 1 or is not a Lucas number). A23497

a(n) = b(n) + d(n), where b(n) = (n-th Lucas number > 3) and d(n) = (n-th number that is 1 or 2 or is not a Fibonacci number). A23498

a(n) = b(n) + d(n), where b(n) = (n-th Lucas number > 1) and d(n) = (n-th number that is 1, 2, or 3, or is not a Lucas number). A23501

a(n) is the least k for which x(k) > ∑_j=1..k 1/j, where x(k) is the Newton iterate (starting from x(1)=1) for exp(-P(n,x)) and P(n,x) is the n-th Maclaurin polynomial for exp(x). A348126
