We prove that every regular expression of size n can be converted into an equivalent nondeterministic =-free finite automaton (NFA) with O(n(log n) 2 ) transitions in time O(n 2 log n). The best previously known conversions result in NFAs of worst-case size 3(n 2 ). We complement our result by provi
