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. b4 ⇒ 1 [2]
2. ba ⇒ ab2 [3]
# ab:babb=a,bbbb=1 b/a - -
bbbb=1
ba=abb
