Alternative first level tubulating tetraflexagon cutout


  
Figure 8: Top side of the alternative first level tubulating tetraflexagon cutout, characterized by the sign sequence (+ + + +). The figure, taken with its backside, makes one single flexagon consisting of two sectors.

Figure 10: Top side of the first level normal rhomboidal tetraflexagon cutout. Together with its backside, the figure contains one single tetraflexagon. Three sectors are required to make some of the faces lie flat on account of the $60^\circ $ angles.
