Minimum Sprocket - Low sprocket: 28T / Top sprocket:11T (front double) / 20T Low sprocket: 25T / Top sprocket:11T(front triple)
In the above example, what does the 20T refer to?
Probably the front difference though it's not entirely clear from how your copy/paste turned out. Try looking at it in tabular form here
