Let  f  be a continuous map of a closed, bounded interval into itself. A criterion is given to determine whether or not  f  has a periodic point whose period is not a power of 2, which just depends on the periodic orbits of  f  whose period is a power of 2. Also, a lower bound for the topological entropy of  f  is obtained.

Simple periodic orbits of mappings of the initial
