The system was reversed.

Remains to prove termination of the 2-rule system
{ a a a a -> a a a b ,
  b b -> b a a }


Loop of length 9 starting with a string of length 10 using right expansion
and the encoding {a=a, b=b}:

.bb.aaabaaab
	rule bb -> baa at position 0
.baa.aaabaaab
	rule aaaa -> aaab at position 2
.baaaab.baaab
	rule aaaa -> aaab at position 1
.baaabb.baaab
	rule bb -> baa at position 5
.baaabbaa.aaab
	rule aaaa -> aaab at position 7
.baaabbaaaab.b
	rule aaaa -> aaab at position 6
