\title{Bertrand's postulate}
\author{Julian Biendarra, Manuel Eberl}
\maketitle

\begin{abstract}
Bertrand's postulate is an early result on the distribution of prime numbers: 
For every positive integer $n$, there exists a prime number that lies strictly 
between $n$ and $2n$.

	The proof is ported from John Harrison's formalisation in HOL Light~\cite{hollight}. It proceeds 
by first showing that the property is true for all $n$ greater than or equal to 600 
and then showing that it also holds for all $n$ below 600 by case distinction.
