OEIS Sequences

Least n-gap prime: a(n) = least prime p for which there is no prime between n·p and n·q, where q is the next prime after p. A195325

Primes p with q = p + 2 and prime(q) + 2 both prime. A236457

Number of partitions of n such that 2*(greatest part) <= (number of parts). A237752

a(n) is the largest term encountered on the path to 0 when iterating the map x -> x', and starting from x = A351255(n). Here x' means the arithmetic derivative of x, A003415. A351261

First noncomposite number reached when iterating the map x -> x', when starting from x = A351255(n). Here x' is the arithmetic derivative of x, A003415. A351259

a(n) = Least i in range [A165598(n),A165598(n+1)] for which abs(A165597(i)) gets the maximum value in that range. A165599

Lesser of the pairs of twin primes in A001122. A319248

Expansion of ∏_k>0 (1+sqrt(1+4·x^k))/2. A327683

Consider triangle in which n-th row contains the smallest set of n consecutive numbers whose LCM is divisible by primorial(n) (the product of first n primes). Sequence contains the first column. A83130

Primes p such that p-3 and p+3 are divisible by a cube. A89201
