      Exact analytical solution is obtained for 3D non-stationary problem of motion of homogeneous initially immovable polytropic gas inside an infinite three-edged angle restricted by three planes, when one of them is promptly removed at t = 0, another plane begins to move into the gas according to some law, and the third plane is immovable rigid wall.
