Properties

Commutative structure

Finite structure

The order of x is the least n such that xn = 1.

Staircase diagram

Right Cayley graph

Rewriting system

Format:
Word:
Enter a word above to compute its normal form. Tips:
  • Lowercase letters stand for generators.
  • Spaces are ignored.
  • Numbers repeat the previous letter, e.g. b90.
