Properties

Finite structure

Elements in the center commute with all other elements.
An idempotent element x satisfies x2 = x.
The index and period of x is the least m (index) and n (period) such that x(m+n) = xm.

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.

#RuleProof
1. ab ⇒ a2 [1]
2. b6 ⇒ b [2]
3. a7 ⇒ a2 [3]
# ab:ab=aa,bbbbbb=b ab - -
ab=aa
bbbbbb=b
