OEIS Sequences

List of triples (r,s,t): the matrix M = [[1,4,4][1,3,2][1,2,1]] is raised to successive negative powers, then (r,s,t) are the square roots of M[3,1], M[1,1], M[1,3] respectively. A249577

Expansion of g.f. (1+x)*(3+x)/(1+6·x²+x⁴). A100434

a(n) = 2·a(n-1) + a(n-2), with a(0) = 1, a(1) = 2, a(2) = 4. A52542

a(n) = 6·a(n-1) - a(n-2). A5319

A005319 and A002315 interleaved. A143608

Numerators of fractions in a 'zero-transform' approximation of sqrt(2) by means of a(n) = (a(n-1) + c)/(a(n-1) + 1) with c=2 and a(1)=0. A163271

Numerators of "Farey fraction" approximations to sqrt(2). A119016

Numerators of principal and intermediate convergents to 2^1/2. A143607

Series ratios converge alternately to sqrt(2) and 1+sqrt(1/2). A82766

Start with the sequence S(0)={1,1} and for k>0 define S(k) to be I(S(k-1)) where I denotes the operation of inserting, for i=1,2,3..., the term a(i)+a(i+1) between any two terms for which 4a(i+1)<=5a(i). The listed terms are the initial terms of the limit of this process as k goes to infinity. A82981
