It seems to me that every element of Z_45 has order 1, 3, 5, 9, 15, or 45. It seems impossible to have an element of order 2 by Lagrange's Theorem.
Is there another way of looking at this problem?

The order of elements in a group is determined by their atomic number, which is based on the number of protons in the nucleus. This number increases from left to right and top to bottom on the periodic table, resulting in a specific order for the elements.
The order of elements in a group is primarily influenced by the number of protons in the nucleus, but other factors such as electron configuration, atomic mass, and chemical properties can also play a role.
The order of elements in a group allows us to make predictions about their properties because elements with similar atomic structures tend to exhibit similar chemical and physical properties. This helps to categorize and organize the vast number of elements on the periodic table.
While the order of elements in a group generally follows the pattern of increasing atomic number, there are a few exceptions. For example, in the transition metals group, elements with lower atomic numbers may be placed after elements with higher atomic numbers due to their similar electron configurations.
The order of elements in a group reflects their relationship in terms of atomic structure and properties. Elements in the same group have similar outer electron configurations and exhibit similar chemical and physical properties. This allows us to understand their relationship and make predictions about their behavior in reactions.
