The current release 2026.3.1 of database_knotinfo contains several changes that require minor adjustments. Specifically, these are the following changes:

  1. The brackets in braid_notation have been changed from {} to [] (for knots only; the values for proper links remain unchanged).
  2. The content of braid_notation for knots with 13 crossings has been improved.
  3. Values for the kauffman_polynomial have been added for knots with 13 crossings.
  4. White-spaces have been added to the values of the homfly_polynomial.

This PR implements the according adjustments. On this occasion, a bug (a misplaced import statement) related to the Regina interface, which occurred during testing, was fixed.
