# Math Help - Markov Chain

1. ## Markov Chain

Hi
I'm trying to find (if it's possible) an irreducible Markov chain with 8 states and period 2. I understand the meaning of irreducible and period, just need to find the markov chain. Can anyone help??
thanks

2. I mean, you could just manufacture it so that every i, j communicate both ways...

i<---->j<---->k
^
|
v
l

etc...

This is irreducible, 8 state with period 2.
