OEIS Sequences

Numbers n such that n²⁰⁴⁸ + (n+1)²⁰⁴⁸ is prime. A274235

Number of maximal squarefree words of length n over the alphabet {0,1,2}. A282212

Expansion of e.g.f.: 1/(1 - x*(1+x)^x). A362238

G.f.: A(x) = F(0,x) where F(0,x) = 1/(1 - x·F(1,x)), F(1,x) = 1/(1 - 4·x*F(2,x)²)^1/2, F(2,x) = 1/(1 - 9·x/F(3,x)³)^1/3, F(3,x) = 1/(1 - 16·x/F(4,x)⁴)^1/4, ..., so that F(n,x) = 1/(1 - (n+1)²*x·F(n+1,x)ⁿ⁺¹)^1/(n+1) for n>=0. A243195

Numbers whose base-11 representation has the same nonzero number of 0's and 1's. A39438
