Hepta Mystery is the seven-fold-symmetry variation of Hollow Mystery (3-fold symmetry) and Rocket Star (5-fold symmetry). Like the other two, it has three canonical state: "base", "left" and "right". In Hepta Mystery, "base" has seven-fold rotation symmetry, and "left" and "right" have two-fold rotation symmetry. "Base" has mirror symmetry. "Left" is mirror image of "right". The types of possible move squences are as follows, every time returning at "base".
Base - left - base
Base - right - base
Base - left - right - base
Base - right - left - base
Base - left - right - left - base
