The second frieze group, F2, contains translation and glide reflection symmetries. According to Conway, F2 is called a STEP.
The third frieze group, F3, contains translation and vertical reflection symmetries. Conway named F3 a SIDLE.
The fourth frieze group, F4, contains translation and rotation (by a half-turn) symmetries. According to Conway, F4 is called a SPINNING HOP.
The fifth frieze group, F5, contains translation, glide reflection and rotation (by a half-turn) symmetries. Conway calls F5 a SPINNING SIDLE.
The sixth frieze group, F6, contains translation and horizontal reflection symmetries. Conway named F6 a JUMP.
Finally, the seventh frieze group, F7, contains all symmetries (translation, horizontal & vertical reflection, and rotation). According to Conway, F7 is named a SPINNING JUMP.
