The image of the same modular folding pattern rotated in π/4 [rad] (45° in degree) of (5√2 + 1) [units] × (5√2 + 1) [units] square:

Since √2 = 1.41421356..., 5√2 + 1 = 8.0710678... as calculated, so that a square of (5√2 + 1) [units] × (5√2 + 1) [units] is as large as that of 8 [units] × 8 [units] ; however, it seems that each image above gives slightly different impression.
Material: the picture and graphic image appeared in the preceding article; with using Adobe(R) Photoshop(R) 5.0 LE -- it is impossible to use 'adhesives' on digital images...
