Description

Basic graph patterns with repeated variables are not available in graphs defined with a variable.

Use the following mapping patterns (actual positions are variable):

($x $x * *) -> ($x $x1 * *) AND ($x1 $x * *)

($x $x $x *) -> ($x $x1 $x2 *) AND ($x2 $x $x1 *) AND ($x1 $x2 $x *)

($x $x $x $x) -> ($x $x1 $x2 $x3) AND ($x3 $x $x1 $x2) AND ($x2 $x3 $x $x1)
