+## `sucℤ`
+
+- Setup the definition of `sucℤ` so that it looks of the form :
+ ```agda
+ Name : TypeOfSpace
+ Name inputs = ?
+ ```
+
+ Compare it with our solutions in `1FundamentalGroup/Quest1.agda`
+- We will define `sucℤ` the same way we defined `loop_times` :
+ by induction.
+ Do cases on the input of `sucℤ`.
+ You should have something like :
+ ```agda
+ sucℤ : ℤ → ℤ
+ sucℤ pos n = ?
+ sucℤ negsuc n = ?
+ ```
+- For the non-negative integers `pos n` we want to map to its successor.
+ Recall that the `n` here is a point of the naturals `ℕ` whose definition is :
+ ```agda
+ data ℕ : Type where
+ zero : ℕ
+ suc : ℕ → ℕ
+ ```
+ Use `suc` to map `pos n` to its successor.
+- The negative integers require a bit more care.
+ Recall that annoyingly `negsuc n` means "`- (n + 1)`".
+ We want to map `- (n + 1)` to `- n`.
+ Try doing this.
+ Then realise "you run out of negative integers at `-(0 + 1)`"
+ so you must do cases on `n` and treat the `-(0 + 1)` case separately.
+
+
+ Hint
+
+ Do `C-c C-c` on `n`.
+ Then map `negsuc 0` to `pos 0`.
+ For `negsuc (suc n)`, map it to `negsuc n`.
+
+
+
+- This completes the definition of `sucℤ`.
+ Use `C-c C-n` to check it computes correctly.
+ E.g. check that `sucℤ (- 1)` computes to `pos 0`
+ and `sucℤ (pos 0)` computes to `pos 1`.
+
+## `sucℤ` is an isomorphism
+
+- The goal is to define `predℤ : ℤ → ℤ` which
+ "takes `n` to its predecessor `n - 1`".
+ This will act as the (homotopical) inverse of `sucℤ`.
+ Now that you have experience from defining `sucℤ`,
+ try defining `predℤ`.
+- Imitating what we did with `flipIso` and
+ give a point `sucℤIso : ℤ ≅ ℤ`
+ by using `predℤ` as the inverse and proving
+ `section sucℤ predℤ` and `retract sucℤ predℤ`.

+## Subject info
+
+- has some experience with type theory and haskell
+
+## Quest0/Part0
+
+- clarify the notation `a : A`
+- hide the imports
+- definition of inductive type doesn't make sense
+ without the further details.
+- confusion of `{!!}` and `{0}` and `?`
+- comparing holes to agda-info window is intuitive
+- error on firsts refine
+- add at each step what the agda-info window looks like
+- confusion about hole numbers. "just ignore them"
+- subject tries to read constraint in agda-info window.
+ Shld deal with this somehow.
+- emphasize no need to fill holes in order.
+
+## Quest0/Part1
+
+- subject confused about 'space of spaces'.
+ More specifically, need to say `a : A` means "`a` is a point of the space `A`".
+- we shld say `a ≡ b` means space of paths from `a` to `b`.
+- 'contradiction' is a pre-existing concept in subject brain.
+- "not sure that helps" - subject about definition of `Bool`
+- "is `flipPath` taking a point from `Bool` to another point of `Bool`
+ or is it taking a space to another space?"
+- "just some terminology" - subject on the definition of _fiber_.
+ Subject did not take in the picture of what it is called fiber.
+- need to add earlier how to check goal of holes.
+- need to be clear _we are assuming `flipPath` is constructed already_.
+- overall : need to be clearer that `Type` is space of spaces,
+ and paths in `Type` are saying which spaces are the same.
+
+## Quesst0/Part2
+
+- For the `iso` bit, change to just `C-c C-r` cuz `Iso` only has one constructor.
+- say you can check def of `Iso` by using `SPC c d`
+- say "just write `s` and `r` and write the rest then load".
+- emphasize agda is indentation sensitive.
+- subject unexpectedly extracts lemma `true ≡ true`.
