[Little Horn of Daniel 8] Is a horn out of a horn, a "horn of littleness." It is insignificant compared to the four "notable horns" and the one original Alexandrine horn of the goat. [Little Horn of Daniel 7] 
Is "more stout than his fellows" (v. 20). In other words, it represents a power that is stronger than those symbolized by the 10 other horns.
