In a city no two persons have identical set of teeth and there is no person without a tooth. Also no person has more than $32$ teeth. If we disregard the shape and size of tooth and consider only the positioning of the teeth, then the maximum population of the city is
${2^{32}}$
${(32)^2} - 1$
${2^{32}} - 1$
${2^{32 - 1}}$
