Another grammar with infinite ambiguity. This one shows that the problem of multiple non-trivial paths does not arise only horizontally with regular-right-part grammars, but can be created vertically as well; the set of derivations is the same as the set of paths through the right-hand side of S in sample.grammar.25.
