I am looking for software/online tool that works on Braid Groups. I am aware that there are resources that allows you to draw braids by imputing generators or detect whether two braids are equivalent or not. I am looking for a more "interactive" one. Namely, after drawing a braid, I am hoping to drag the strings to form a new (equivalent) braid by myself. If I can manually click on an over-crossing and switch it to an under-crossing or vice versa that would be ideal.
Anyone knows such a software/online tool, or knows the non-existence?
