So, you are saying that from this file

After splitting and symmetrizing, I will arrive at this

Now, oxygen had multiplicity 6 and now it has 1. Is this correct? Also

The original cell has 10 atoms and this one has much less and it is quite different from the original.

===============

The crystal is SG 161, I only put the fist position.
There are two Fe1 (up), two Fe2 (dn) and 6 O

I started with the 'P' lattice (above) and from the 4 Fe I took the 1st and 3th as Fe2 and 2nd and 4th as Fe1
You can play other combinations, but this seems the best; each O has two Fe1and two Fe2 forming a cross.
