Study the gate carefully, noting that the two centre poles (5 and 6) have decorations on them and they also cannot be rotated. The area between these two poles must be cleared to open the gate, so bars C, D, E and H must be moved. In order to do this the other bars must first be moved out of the way.
 
 

 
 
Note: The left circle symbol rotates to the right and the right circle symbol rotates to the left (directions of the V's)
