Formula

Limit of m(i+1)=m(i).x(i).Mir(Bar(m(i))), m(1)=0; Mir is the antimorphism Mir(mm')=Mir(m)Mir(m'), Bar the alphabetic morphism Bar(0)=1, Bar(1)=0 and x(i) the letter of rank i into the limit.

Example

m(1)=.0., m(2)=0.0.1, m(3)=001.0.011, m(4)=0010011.1.0011011, m(5)=001001110011011.0.001001100011011
