In Granny Simulator there are two players, a feeble old grandmother and her lovely grandson. The grandmothers objective is to complete her every day routine while the grandson utilizes uncanny violence and pure brutality to stop her.
In geometry, the Cairo pentagonal tiling is a dual semiregular tiling of the Euclidean plane. It is given its name because several streets in Cairo are paved in this design. It is one of 15 known monohedral pentagon tilings.
It is also called MacMahon's net after Percy Alexander MacMahon and his 1921 publication New Mathematical Pastimes.
Conway calls it a 4-fold pentille.
As a 2-dimensional crystal net, it shares a special feature with the honeycomb net. Both nets are examples of standard realization, the notion introduced by M. Kotani and T. Sunada for general crystal nets.
Geometry
These are not regular pentagons: their sides are not equal (they have four long ones and one short one in the ratio 1:sqrt(3)-1), and their angles in sequence are 120°, 120°, 90°, 120°, 90°. It is represented by with face configuration V3.3.4.3.4.
It is similar to the prismatic pentagonal tiling with face configuration V3.3.3.4.4, which has its right angles adjacent to each other.
Variations
The Cairo pentagonal tiling has two lower...
