Abstract
In pushdown automata, states can sometimes do more than stack symbols. More precisely, reducing the state set by a factor of k may require an increase in the stack alphabet by a factor of k2. These results are based on the observation that the "triple construction" for converting a pushdown automaton into a context-free grammar is optimal.
