I forget the proper terminology! But the DFA is shown below. The alphabet is {0,1}. Reading 000 you go in a 3-cycle from q₀ to q₀. Given this you can fill in all edge labels. The big diagram above indicates that states (q₀,q₁,q₂) go to (q₁,q₂,q₀) when reading a 0, by having an arrow from 012 to 120.

They have different types so they can't be compared as = or not =.
