# Example Ugly Data Format Files
These are example files that you can use with the `parse_magic.py` script.
## R6
Contains all models of R up to size 6.
## R4-MN
Contains all models of a fragment of R without negation up to size 4.
## R3-PN
Extends R to have necessitation with the following additional axioms:
1) p / !p
2) !(p -> q) -> (!p -> !q)
3) (!p & !q) -> !(p & q)
Output contains all satisfiable models up to size 3.
## R5-S5
Extends R with axioms that classically are adequate for S5 giving rise to an R-ish version of S5 with necessitation.
