I am not sure but this is what i am thinking

 

Any on of the 7 can go in the middle 

Place one more is a specific spot - Say the red one 

There are 5 more places to fill so that is 5!

 

Now if the middle one and one side one is fixed then there is only one axis of symmetry that counts,  I mean the one that goes through the centre one and the red one.

 

So maybe the answer is

 

\(\frac{7*5!}{2}=7*3*4*5=420\)

 

I am ot sure though.
