  Chemical short range order and topology of Ge$_{x}$Ga$_{x}$Te$_{100-2x}$
glasses was investigated by neutron- and x-ray diffraction as well as Ge and Ga
K-edge extended x-ray absorption fine structure (EXAFS) measurements. Large
scale structural models were obtained by fitting experimental datasets
simultaneously with the reverse Monte Carlo simulation technique. Models,
relying only on experimental data and basic physical information without
constraining the average coordination numbers, give 3.9 - 4.1 for the number of
the atoms in the first coordination sphere of Ge atoms, while the average
number of first neighbors of Ga atoms scatters around 3.8. The average
coordination number of Te atoms is significantly higher than 2 for $x$ = 12.5
and 14.3. It is found that the vast majority of MTe$_4$ (M=Ge or Ga) tetrahedra
have at least one corner sharing MTe$_4$ neighbor.
