| Abstract: | We consider the problem of computing the entropy of a braid. We recall its definition and for each braid construct a sequence
of real numbers whose limit is the braid’s entropy. We state one conjecture on the convergence speed and two conjectures on
braids that have high entropy but are written with few letters.
