Hi Adam,

Thank you for the precisions. You are right, we don't have the other two.

I guess that we could/should add them...

Hi Monica,

Thank you for your reply.

It looks like "flips" implements the (2,3) and its inverse, but not the
(2,6) and (4,4) moves + inverses.

Thank you!

If it does not provide everything you need, we could add more in CGAL.

Hello all,

Before I start implementing my own version, are there Pachner moves
defined in CGAL for triangulations?

Pachner, Udo. “P.L. Homeomorphic Manifolds Are Equivalent by

Shellings.” /European Journal of Combinatorics/ 12, no. 2 (March
1991):

Thanks,
