  Transition from chaotic to ordered state has been observed during the initial
stage of a discharge in a cylindrical dc glow discharge plasma. Initially it
shows a chaotic behavior but increasing the discharge voltage changes the
characteristics of the discharge glow and shows a period substraction of order
7 period $\to$ 5 period $\to$3 period $\to$1 period i.e. the system goes to
single mode through odd cycle subtraction. On further increasing the discharge
voltage, the system goes through period doubling, like 1 period $\to$ 2 period
$\to$ 4 period. On further increasing the voltage, the system goes to stable
state without having any oscillations.
