(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A096055 Let {s(i)}, i=0,1,2,... be a sequence of finite sequences with terms s(i)(j), j=1,2,3,... Start with s(0)={1}. Then, for k>0, let s(k)=s(k-1)Us(k-1) if s(k-1)(k)=0, s(k)=s(k-1)U{0}Us(k-1) if s(k-1)(k)=1, where s(i)(j) is the j-th element of s(i) and U denotes concatenation of the terms of the two operands. {a(n)} is the limit of s(k) as k goes to infinity. 2

EXAMPLE

Let s(0)={1}. Then

s(1)=s(0)U{0}Us(0)={1,0,1}, since s(0)(1)=1,

s(2)=s(2)Us(2)={1,0,1,1,0,1}, since s(1)(2)=0,

s(3)=s(2)U{0}Us(2)={1,0,1,1,0,1,0,1,0,1,1,0,1}, since s(2)(3)=1, etc.
