There is also possibility to read saved polynomials from a file. The file [homflypt.input](homflypt.input) in the repository contains HOMFLYPTY polynomials for some knots, but to make it work properly knots should be analyse in the same order as their polynomials are saved in the file [homflypt.input](homflypt.input).
### Input data ### Input data
Files with PD-codes for all knots up to 15 crossing are available in the repository (`knots_11_15.txt` and `knots_3_10.txt`) and should be saved in the same folder as the script or a path in the `class MySettings` should be adjusted. Similarly, if other input files will be used, settings have to be changed. A correction in parsing or reading functions may be also necessary (`check_11_to_15()`, `check_up_to_10()`, `parse_pd_code()`, `parse_knot_name()`).

### Versions
There are two versions of the script in the repository. The version [verbose_periodicity](verbose_periodicity.sage) was used for calculations and tests. The another version - [periodicity.sage](periodicity.sage) - is free of tests fragments and more easy to read.
### Running in terminal ### Running in terminal
The script should be run in terminal: `sage periodicity.sage`. The script should be run in terminal: `sage periodicity.sage`.
