denotes that two diagrams are reversible each other.
The alternate twisting pattern that is in reflection to the twisting pattern in the preceding article and variations of bird bases induce the following (flatly foldable) diagrams:
The alternate twisting pattern, which has been appeared as one of diagrams in the second case at the previous article: On 90°twisting: diagrams.
There exist ten different (flatly foldable) diagrams of cruciform shapes; each of these is composed of an alternate twisting pattern and a variation of bird bases.
Foldable arrangements of reversed bird bases combined with 90°[π/2 (rad)] counter-twisting patterns induce the following diagrams, each of which corresponds to its reversed diagram appeared in the previous article: Cruciform shapes: diagrams.
