- Maximally Transient
- No Disabling Inputs (Zinp)
- Disabling outputs (Zout) in state(s):
- 3
- Order-Independent input (Yinp)
- Order-Independent output (Yout)
- Output refusal sets do NOT propagate backward over inputs in state(s):
- 2
- Output Non-Deterministic

- All states are reachable from the initial state:
[ + == 9 < distance < +inf , . == distance = +inf ]
Initial state reachable from all states.
All states reachable from all other states.
- Shortest paths from initial state:
-
- Distribution of distances from initial state:
[d=distance, h=occurrence count, c=cumulative occurrence count] -
d: | h | [c] |
0: | 1 | [1] |
1: | 2 | [3] |
2: | 1 | [4] |

- There are 2 state pairs (x,y) where x refines y outside the diagonal:
- (0[],1[]) (2\/,3\/)
