In this third part, let us look at AAAB, ABBB, ABBA, and AABB patterns. The prior parts, part 1 can be found here, part 2 can be found here.

All the patterns mentioned above except ABBA are all registered as of scan done 15-20 days back. It might also be possible that even all ABBA are registered. As noted previously, the taken pattern follow the prices commanded by LLLL.COMs and hence these are eagerly picked up. The thing about ABBA names is that if the A is a consonant and B turns out to be a vowel, then the name can be easily pronounceable. Examples of these names are BAAB.in, MOOM.in, PEEP.in, etc.

**The total number of different AAAB.in patterns:** Doing the math we get 26 X 25 (650) combinations. These can be found here.

**The total number of different ABBB.in patterns:** Doing the maths we get 26 X 25 (650) combinations. These can be found here.

**The total number of different AABB.in patterns:** Doing the maths we get 26 X 25 (650) combinations. These can be found here.

**The total number of different ABBA.in patterns:** Doing the maths we get 26 X 25 (650) combinations. These can be found here.

Unfortunately, the above patterns can be either fall into only one of the buckets only. So, what that means is that if a name is AAAB, it cannot be any of ABBB, AABB or ABBA. This leads to a rather bland Venn diagram which I will not even bother posting.
