Consider the alphabet $$\sum { = \left\{ {0,1} \right\},} $$ the null/empty string $$\lambda $$ and the sets of strings $${X_0},\,{X_1},$$ and $${X_2}$$ generated by the corresponding non-terminals of a regular grammar. $${X_0},\,\,{X_1},\,$$ and $${X_2}$$ are related as follows.
$$$\eqalign{
& {X_0} = 1\,X{}_1 \cr
& {X_1} = 0{X_1} + 1\,{X_2} \cr
& {X_2} = 0\,{X_1} + \left\{ \lambda \right\} \cr} $$$
