Properties

Elements

Elements in the center commute with all other elements.
The order of x is the least n such that xn = 1.

Rewriting system

Format:
Word to reduce:
Tips:
  • Lowercase letters stand for generators.
  • Spaces are ignored.
  • Numbers repeat the previous letter, e.g. b90.

#RuleProof
1. a24 ⇒ 1 [13]
2. ab ⇒ ba19 [12]
3. b2 ⇒ a4 [1]
# ab:aaaa=bb,abab=1 a/b
aaaaaaaaaaaaaaaaaaaaaaaa=1
ab=baaaaaaaaaaaaaaaaaaa
bb=aaaa
