I am not convinced that there is any better or faster check for an inconsistent/unreachable cube than trying to solve it and blowing out: ... You mean I haven't convinced you of that yet? Show me how your cube is represented and I will write one for you. What would be so bad about blowing out anyway? What happens when you hand a person an impossible cube? his algorithm "blows out" eventually! There is no shame in being tricked into trying to solve a bad cube.
