Emily has 8 differently colored beads and wants to create a symmetrical necklace by placing 4 beads on one side and 4 beads on the other side of a central bead (the central bead can be one of the 8 beads). She wants to ensure that each half of the necklace is a mirror image of the other half. How many distinct symmetrical necklaces can Emily create? Let's think step by step and output the final answer within \boxed{}.
