R' Yochanan's chiddush about an acceptable place for shechting kodashim kalim is, seemingly inexplicably, ommited from its proper place in Eizehu Mekoman.

The sugya of אף על פי שנסע אהל מועד הוא is fragmented into three sugyos, one of them ours.

A nine part tour through the history and features of the Mizbeiach

Unraveling the components of this two part sugya

Mapping out the general contours of the two sugyos leading up to the next Mishnah and how they relate back to our previous sugyos

Two self-contained Tannaic disputes about the measurements of the Mizbeiach in the Mishkan are brought here (and only here) in purely supportive roles for a different discussion.

An important, self-contained sugya appears only here, summoned in tangential service of a different topic.

A conceptually unrelated halachah, sparking an entire spectrum of attendant sugyos, appears in our perek because it is derived from the passuk that serves as the source of the halachah in our Mishnah.

The source for the very fundamental requirement of shefichas shirayim with korbanos other than chattas turns up tangentially in our unrelated sugya and will never be revisited.

The existential question of whether or not Pesach and Ma'aser are even korbanos is buried in a conceptually unrelated sugya in the "wrong" Perek.
