The adjacency matrix I have at the start is  
[0,1,0,0,0]  
[0,0,1,0,0]  
[1,0,0,1,1]  
[0,0,0,0,0]  
[0,0,0,0,0]  

I don't understand why this matrix^9999 equals  
[1,0,0,1,1]   
[0,1,0,0,0]  
[0,0,1,0,0]   
[0,0,0,0,0]  
[0,0,0,0,0]    

or why this matrix^33334 equals  
[0,1,0,0,0]  
[0,0,1,0,0]   
[1,0,0,1,1]   
[0,0,0,0,0]  
[0,0,0,0,0]  


can someone please explain what is happening?
