Parent State ID: 23
State Depth: 6
Action Taken: put-down(c)
Action Reasoning: To achieve the goal state, we need to place block 'c' on the table, making it clear and supporting, so that block 'b' can be stacked on it.
State Description: Block 'c' is now on the table and clear. Block 'b' remains clear and on the table. Block 'a' is on top of block 'd', and block 'd' is supporting block 'a'. The hand is empty.
Action Path: ['unstack(d, a)', 'put-down(d)', 'pick-up(a)', 'stack(a, d)', 'unstack(c, b)', 'put-down(c)']
