Dukpt AES-192 and AES-256 derive key calculation

Question

In many places and for different programming languages we can find how to calculate derivation key for IK length 32 which will work for AES-128, but AES-192 and AES-256 use keys bigger size, for example:

AES-128 key: 6AC292FAA1315B4D 858AB3A3D7D5933A
AES-192 key: 6AC292FAA1315B4D 858AB3A3D7D5933A 6AC292FAA1315B4D
AES-256 key: 6AC292FAA1315B4D 858AB3A3D7D5933A 6AC292FAA1315B4D 858AB3A3D7D5933A

I'm trying to find example implementation algorithm how to calculate derivation key for these long size initial keys.
