Name for "3D quadrilateral" shape? I am interested to know the name of the following solid construction - kind of a deformed cube... but I don't know the name, or even a general name:


Left and right faces parallel with the $yz$ axes
Bottom face parallel with the $xz$ axes
Back face parallel with the $xy$ axes.
Front and top faces not necessarily parallel,


assuming $x=(1, 0, 0),y=(0,1,0),z=(0,0,1)$. If there is no such name, then is "3d quadrilateral" correct ?
This is a right-quadrilateral-based right prism. Say prism for short.
It is called Triclinic. It is one of the 7 crystal systems.
