multidimensional arithmetic progression

An $n$ -dimensional arithmetic progresssion is a set of the form

	$\displaystyle Q$	$\displaystyle=Q(a;q_{1},\ldots,q_{n};l_{1},\ldots,l_{n})$
		$\displaystyle=\{\,a+x_{1}q_{1}+\cdots+x_{n}q_{n}\mid 0\leq x_{i}<l_{i}\text{ % for }i=1,\ldots,n\,\}.$

The length of the progression is defined as $l_{1}\cdots l_{n}$ . The progression is proper if $|Q|=l_{1}\cdots l_{n}$ .
