We investigate the deterministic and nondeterministic state complexity of languages that can be obtained as the concatenation of two regular languages represented by deterministic and nondeterministic finite automata. In the nondeterministic case, we show that the whole range of complexities from 1 to m + n can be obtained using a binary alphabet. In the deterministic case, we get the whole range of complexities from 1 to m ·2 n *** 2 n *** 1, however, to describe appropriate automata we use a growing alphabet.
