## Copy constraints
|

## Equality constraints
|
||||
- Define permutation between a set of columns, e.g. $\sigma(a, b, c)$
|
||||
- Copy specific cells between these columns, e.g. $b_1 = c_0$
|
||||
- Assert equalities between specific cells in these columns, e.g. $b_1 = c_0$
|
||||
- Construct permuted columns which should evaluate to same value as original columns
