 These can be represented in CuTe as:
 - *SFA Layout*: $((\text{scale granularity M}, M / \text{scale granularity M}), (\text{scale granularity K}, K / \text{scale granularity K})) : ((0, int), (0, int))$
-- *SFB Layout*: $((\text{scale granularity N}, M / \text{scale granularity M}), (\text{scale granularity K}, K / \text{scale granularity K})) : ((0, int), (0, int))$
+- *SFB Layout*: $((\text{scale granularity N}, N / \text{scale granularity N}), (\text{scale granularity K}, K / \text{scale granularity K})) : ((0, int), (0, int))$
 
 The 0 element stride ensures the same group of coordinates to map to the same element in the scale factors.
