@ -75,14 +75,14 @@ For example, for the most sensible instance, use this:
```Haskell
data StateSpace = Store [Atom] | Check [Atom] | Accept | Reject
deriving (Eq, Ord, GHC.Generic)
deriving Nominal via Generic DoubleWord
deriving Nominal via Generic StateSpace
```
If, however, you want a trivial group action on your data structure. (This is
used for the data structure for equivariant sets.) Then you can use this:
```Haskell
newtype EquivariantSet a = EqSet { unEqSet :: Set (Orbit a) }
newtype EquivariantSet a = ...
deriving Nominal via Trivial (EquivariantSet a)
```
