The electronic structure of La 7/8 Sr 1/8 MnO 3 was studied by using the rotation-invariant LSDA (Local Spin Density Approximation)+U formalism. We found the specific kind of charge and orbital order for ferromagnetic insulating solution in 2a*2b*4c supercell, where a, b, and c denote cubic perovskite axes. The holes are distributed over 3-line stripes in every second ac plane along a axis. The stabilization mechanism of the hole stripe is attributed to the strong p-d hybridization.
