### Choice, Order Dependence, Nondeterminism

• Maximally Transient
• Disabling inputs (Zinp) in state(s):
0
• No Disabling Outputs (Zout)
• Order-Independent input (Yinp)
• Order-Independent output (Yout)
• Output refusal sets propate backward over inputs
• Output Deterministic

### Distances

All states are reachable from the initial state:
[ + == 9 < distance < +inf , . == distance = +inf ]
01234
0:01123

Initial state reachable from all states.
All states reachable from all other states.

Shortest paths from initial state:
0: r t r a r a t

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]
3:1[5]
