Properties

Appears in sequences

• a(1) = 1; thereafter a(n) is the smallest number > a(n-1) such that a(n) minus any sum of distinct earlier terms is not already in the sequence.at n=14A066425
• Engel expansion of exp(2).at n=18A068375
• Partial sums of ceiling(Fibonacci(n)/4).at n=25A179042
• Let b(n,0) = n and b(n,k) = 2*b(n,k-1) + 1 for k > 0. Then a(n) = b(n,1) + b(n,2) + ... + b(n,n).at n=10A190730
• Primes whose hexadecimal representation contains only consonants.at n=25A238090
• Expansion of (1+x)/(1-x^2-3*x^3).at n=22A238389
• Numbers k such that (2*10^k + 457)/9 is prime.at n=24A281276
• Coefficients in the power series A(x) such that: A(x) = Sum_{n=-oo..+oo} x^(2*n+1) * (1 - x^n)^(n+1) * A(x)^n.at n=8A357151
• Expansion of (1+2*x+x^2) / (1-x-5*x^2-2*x^3).at n=10A384648
• Prime numbersat n=5048
