In how many ways can seven beads of distinct colors be put on the hexagonal grid shown, if rotations of an arrangement are considered equivalent?

7 * 5!   sounds good to me.

 

Put one in the middle, 7 possibilities.

Take one at random and put it in a position.  This marks the ästart of the outer ring.

 

Then there are 5 left so they can be ordered in 5! ways
