This group consists of the following 25 tetrahedrons.
| (1) (2) |
(41) (42) |
(141) (241) (142) (242) |
(4141) (4241) (4142) (4242) |
(14141)* (24141) (14241) (24241) (14142) (24142) (14242) (24242)* |
(414141)** (424141) (414241) (424241) (414142) (424142) (414242) (424242)** |
* all these matrices are the same as (4) so only one is counted
** all these matrices are the identity matrix so none are counted
A projection of this shape onto a plane follows.
