Is there a reason why you did setup this case in P1 symmetry ???
You seem to have Fe18 Ga24, which is the same as Fe3 Ga4
What happens when you remove all "labels" (1,2,3,... 24) of the atoms ?
Wien2k will then find out which atoms are equivalent and which are
different by symmetry.
Maybe this is even a C-centered monoclinic structure ?
Anyway, when you have a structure which has only a "few" (2-4)
nonequivalent Fe positions, then it makes sense to play with magnetic
order and compare total energies.
You would start in different directories and BEFORE init_lapw run
instgen_lapw -ask and specify the desired magnetic order by chosing up
or dn for each Fe site (and nm for Ga).
For visualisation you may create a struct file where you rename your
atoms to Co, Ni,...., so that you can distinguish them in xcrysden and
then you can see how to arrange the magnetic moments to get them in a
specific order.
