The Q45 has a R200 diff. The 200 just means it's a 200mm ring gear. It does indeed have the 6 equally spaced flanges.
They typically refer to the Q diff as the R200 "short nose", however comparing them side by side they're very similar to the Z32 twin turbo diff, despite having the smaller ring gear.
