I plan on deleting everything above this after we have completed the paper.  I planned on just using the outline as a guide. 

I've been using these websites:

P-groups

Definitions:

• Let p be a prime p $ \in $ $ \mathbb{Z} $ such that $ \mathbb{Z} $≥0. A p-group is a group of order pⁿ.
• A subgroup of order p^k for some k ≥ 1 is called a p-subgroup.
• If |G| = p^αm where p does not divide m, then a subgroup of order p^α is called a Sylow p-subgroup of G.

Regular p-groups

Definitons:

• For every a, b $ \in $$ G $, there exists $ \mathlarger{c} $$ /in $$ \mathlarger{{[<a,b>,<a,b>]} $

Sylow's Theorems

Definitions:

Let G be a group of order p^αm, where p is a prime, m≥1, and p does not divide m.  Then:

All Sylow p-subgroups are conjugate in G. To expand, if P₁ and P₂ are both Sylow p-subgroups, then there is some g
