As a follow-up to this question: Is there any configuration of Free Cell that cannot be solved?, is there a FreeCell seed that solves itself? (with the auto card-stack built-in in the game) I know this is possible because the configuration below permits such a thing:
K-K-K-K Q-Q-Q-Q
J-J-J-J T-T-T-T
9-9-9-9 8-8-8-8
7-7-7-7 6-6-6-6
5-5-5-5 4-4-4-4
3-3-3-3 2-2-2-2
A-A-A-A
