1. A blade cascade for a gas turbine, comprising a first group with at least two,first blade arrangements that are of the same type to one another, wherein each blade of the first blade arrangements comprises a first detuner arrangement having at least one first detuner and having only one detuner type movably mounted therein, wherein each first detuner arrangement on each blade of the first blade arrangements is identical to one another; anda second group with at least two, second blade arrangements, which are of the same type to one another and of different type from the first blade arrangements, wherein each blade of the second blade arrangements comprises asecond detuner arrangement having at least one second detuner and having only one detuner type movably mounted therein, wherein each second detuner arrangements on each blade of the second blade arrangements is identical to one another and of different type than the first detuner arrangement on the blades of the first blade arrangements. 2. The blade cascade according to claim 1, further comprising: a third group with at least two, third blade arrangements, which are of the same type to one another and of different type from the first and second blade arrangements, wherein each blade of the first blade arrangements comprises a third detuner arrangement having at least one third detuner and having only one detuner type movably mounted therein, wherein each third detuner arrangement on each blade of the third blade arrangement is identical to one another,wherein first detuner arrangements, second detuner arrangements, and third detuner arrangements are different from one another. 3. The blade cascade according to claim 1, wherein the blade arrangements of at least one of the groups in each case has exactly one blade, on which the respective detuner arrangement is movably mounted. 4. The blade cascade according to claim 1, wherein the blade arrangements of at least one of the groups in each case has a pair of blades that are of the same type or of different type and are adjacent in the peripheral direction, on which the respective detuner arrangement is movably mounted. 5. The blade cascade according to claim 1, wherein detuner arrangements that are identical to one another are movably mounted on a majority of the blade arrangements, which are of the same type to one another, of at least one of the groups. 6. The blade cascade according to claim 1, wherein blade arrangements that are of a different arrangement from one another and being primarily shaped and/or reshaped and/or machined differently and having different contours, weights, weight distributions, and/or monocrystalline materials with different crystal orientations. 7. The blade cascade according to claim 1, wherein the detuner arrangements that are different from one another have a different number of elements and/or elements with different contours, weights, and/or weight distributions, position, orientations, and/or mountings. 8. The blade cascade according to claim 1, wherein at least one detuner of the detuner arrangements is arranged on an outer shroud, an inner shroud, or a blade root of the blade arrangement. 9. The blade cascade according to claim 1, wherein the blade cascade is arranged in an aircraft engine as a configuration selected from the group consisting of a rotor blade cascade and guide vane cascade.
