Rabbit Sequence

A Sequence which arises in the hypothetical reproduction of a population of rabbits. Let the Substitution Map $0\to 1$ correspond to young rabbits growing old, and $1\to 10$ correspond to old rabbits producing young rabbits. Starting with 0 and iterating using String Rewriting gives the terms 1, 10, 101, 10110, 10110101, 1011010110110, .... The limiting sequence written as a Binary Fraction $0.1011010110110\ldots_2$ (Sloane's A005614), where $b_2$ denotes a Binary number (a number in base-2) is called the Rabbit Constant.
