Abstract
It is known that the topological entropy of a continuous interval map is positive if and only if the type of for Sharkovskii's order is for some odd integer and some ; and in this case the topological entropy of is greater than or equal to , where is the unique positive root of . For every odd , every and every , we build a piecewise monotone continuous interval map that is of type for Sharkovskii's order and whose topological entropy is . This shows that, for a given type, every possible finite entropy above the minimum can be reached provided the type allows the map to have positive entropy. Moreover, if the map we build is topologically mixing.
