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.
Strategy:
Result: 1

#RuleProof
1. a13 ⇒ a [4]
2. ab ⇒ ba5 [3]
3. b2 ⇒ a3 [1]
# ab:aaa=bb,baab=a a/b - -
aaaaaaaaaaaaa=a
ab=baaaaa
bb=aaa
