Abstract Algebra
A group element of finite order generates a finite cyclic subgroup of that order.
A group element of infinite order generates an infinite cyclic subgroup.
Cyclic subgroups are equivalent if one power is expressible as the gcd of the other with the order of the base.
Every permutation is the product of disjoint cycles.
Every power of a group element with infinite order is unique.
Every subgroup of a cyclic group is itself cyclic.
For each factor of the order of a cyclic group, the number of elements in the group with the order of that factor is equal to the number of totatives of the factor.
Fundamental Theory of Cyclic Groups
Greatest Common Divisor is expressible as a linear combination of its arguments
Group Cancellation Laws
If a group is finite, then every element has finite order.
Powers distribute over an operation if and only if the group is abelian.
The group center is a subgroup.
The identity element of a group is unique.
The inverse of an element in a group is unique.
The order of a group element divides the difference in exponent of equivalent powers of that element.
The order of a group element to some power is equal to the order of the generator, divided by the gcd of the order of the generator with the power of the element.
The order of any cyclic subgroup divides the order of any cyclic group which contains it.
The product of two elements with finite order which commute in a group has finite order which divides the product of the orders of the elements.
There is exactly one subgroup of the order of each divisor of the order of its container cyclic group.
