:-) I took part of the lunch break to extract some sample code ( of 
course the full code is more complex)...
but you got here the basic idea how to implement your solver, transition 
m is in this test  top face clock turn.

Part of this test is to see how well it handle array ...

And o my machine I stiil got pretty much the same ranking
