Go back to the page of Subsection 2.5.3.

There's a small typo in Construction 2.5.3.1: In the formula at the bottom, in the second index, there should be a $i_{k-1}$ instead of an $i_{m-1}$

Yep. Thanks!

Possible typo in the proof of Proposition 2.5.3.5. (tag 00PQ) :

1. Equation (2.25) (tag 00PR) : possible duplicate $(-1)^a$, and the summation might be within the range $0 instead of $1.
2. In the item "Suppose that the restrction $\alpha\mid_J$ is injective ..." : similarly for range of summation
3. In the next item the tag number of the reference of an equation might be 00PR instead of 00PK
