Hello,

I wanted to talk about question 3B.

It seems that the question has caused a lot of confusion.

some understood that the group En is a finite set, and as we learned, if it's final so it can be calculated.

On the other hand, I understand that your intention in that question was that En is a group that can't be calculated at all, and this is what makes F2 not calculated.

I think that the question was confusing and misleading, and the idea that that the group exists (because is finite coding length, there are finite number of TM like that, so we can know that EN exist (even if we can calculate it ourself).

We will be glad if you could take this question into consideration during the check of the test.

Thank you
