Description
Sarna is a program to calculate the Arithmetic Root System associated to a braid of diagonal type. This software can be used to calculate:
The Weyl groupoid and the set of positive/negative roots,
The generalized Dynkin diagram,
The dimension, the GK-dimension and the Hilbert series of the Nichols algebra.
Also in rank 2 or 3 it is possible to see the set of roots using gnuplot.
