Homework Statement
Show that II18 / <3> is isomorphic to II3.
Homework Equations
II18 = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18}
<3> = {0,3,6,9,12,15}
II3 = {1,2,3}
II18 / <3> = {3,6,9,12,15,18}
Looks to me like your proof says they are NOT isomorphic! If they don't have the same number of members, they certainly aren't isomorphic.aliciaislol said:Homework Statement

The Attempt at a Solution
The isomorphism problem is a mathematical problem that asks whether two structures or objects are essentially the same, despite having different descriptions or representations. It is a fundamental problem in many areas of mathematics, computer science, and chemistry.
Examples of the isomorphism problem include determining whether two graphs are isomorphic, whether two groups are isomorphic, and whether two chemical compounds have the same structure despite having different molecular formulas.
The isomorphism problem is important because it allows us to identify and understand the underlying structure of objects or systems. It has applications in areas such as cryptography, pattern recognition, and the classification of chemical compounds.
Isomorphism and homomorphism are related concepts, but they have different definitions. Isomorphism refers to the equality of two structures, while homomorphism refers to a mapping between two structures that preserves certain properties, such as operations or relationships.
The isomorphism problem is a difficult problem with no general solution. However, there are algorithms and techniques that can be used to determine whether two specific structures or objects are isomorphic. These solutions are often specific to the type of structures being compared.
