Suppose that we find the converse, obverse, or contrapositive of a categorical proposition.Then we find the obverse, converse or contrapositive of the result.If we continue this process forever, how many propositions could be produced that are different from but equivalent to the original?

There are three operations: conversion, obversion, and contraposition. Each operation can be applied to a categorical proposition to produce an equivalent proposition. However, applying these operations repeatedly will eventually cycle through a limited number of equivalent forms. Specifically, for any given categorical proposition, there are three distinct equivalent forms that can be derived through these operations.
