1)

(a) Rav says that the third Tefach-wall should be placed at ninety degrees to one of the other two walls; Rav Kahana and Rav Asi suggest that it should be at an angle.
With whom does Rebbi Simon (or Rebbi Yehoshua ben Levi) agree?

(b) A regular Tefach comprises four Etzba'os.
How is *this* Tefach-wall measured?

(c) How far away from the existing wall is the Tefach-wall placed, and why is that?

(a) According to Rav Yehudah, the same Din of a third Tefach-wall will apply if one has two existing *parallel* walls.
Where does one then place it?

(b) Rebbi Simon (or Rebbi Yehoshua ben Levi) disagrees.
What does he say?

(c) Why, according to Rebbi Simon, is the Din by parallel walls more stringent than by adjacent ones?

(a) Rava requires a Tzuras ha'Pesach.
What is a 'Tzuras ha'Pesach'?

(b) According to the first interpretation, the Tzuras ha'Pesach must stretch across the entire length of the third wall.
How is it arranged?

(c) What are the other two interpretations of Rava's undisputed opinion?

(d) Rav Ashi holds like Rava's *second* explanation. What does Rav Kahana hold?

(a) In which regard does Rabah say that the validity of the third Tefach- wall applies to Shabbos, too? On what grounds does he say it?

(b) Will this 'Migu' apply the whole year round?

(a) In which regard does the Beraisa say that the wall of ...

1. ... a Sukah has the same leniencies as that of Shabbos?
2. ... a Sukah has leniencies that a wall of Shabbos does not?

(b) How is this a Kashya on Rabah's previous Halachah?

(c) We answer that the Beraisa is talking about Shabbos throughout the year (but not on Sukos).
What problem do we have with this answer? What should the Beraisa then have added (regarding the Din of a Sukah on Shabbos)?

(d) It would not be necessary to tell us this, answers the Gemara.
Why not?

6)

(a) Rava permits a Sukah whose walls consist a. of a Mavoy and the Lechi at the entrance, and b. of Pasei Bira'os (four Deyumdin, each of an Amah by an Amah).
Why does he need to state both cases? Why would it not suffice to issue his ruling just in the case of ...

1. ... the Mavoy?
2. ... the Pasei Bira'os?

(b) And why does he also need to permit a Sukah of two walls and a Tefach even on Shabbos because of 'Migu'? Why would we not know that, from the reverse case (i.e. of walls that are valid on Sukos because they are valid on Shabbos [as in 5a 1])?

(a) According to the Tana Kama of the Beraisa, it is only the sunlight that shines through the *S'chach* that can invalidate the Sukah, but not that shines through the *walls*.
What does Rebbi Yoshi'ah say?

(b) How does he learn this from the Pasuk in Pikudei "ve'Sakosa al ha'Aron es ha'Paroches"?

(c) What do the Rabbanan learn from this Pasuk?

(d) We have already learned that Rebbi requires a Sukah to be at least four by four Amos, and that Rebbi Yehudah validates a Sukah that is higher than twenty Amos.
What do they (as well as Rebbi Shimon, who requires at least three full walls, and a third wall of one Tefach), have in common with Rebbi Yoshi'ah?

(a) Raban Gamliel, Beis Shamai, Rebbi Eliezer and Acheirim also subscribe to the same opinion. Beis Shamai invalidate a Sukah, if one's table is in the house.
What does Raban Gamliel say about a Sukah on top of a wagon or a ship?

(b) What does Rebbi Eliezer say about a Sukah in the shape of a wigwam?

(c) Which other case does he include in this Halachah, and what is his reasoning for invalidating such a Sukah?

(d) What do the Chachamim say?

(a) What does Acheirim say about a round Sukah?

(b) Rebbi Yochanan does not rule like Acheirim. According to him, a round Sukah is Kasher, provided twenty-four people can sit round it.
Like which Tana does he in fact, rule? What is the minimum size of a square Sukah, in his opinion?
