The Iranun are a Moro marine-oriented ethnic group from Mindanao, Philippines, and Sabah, Malaysia's west coast (in which they are found in 25 villages around the Kota Belud and Lahad Datu districts; also in Kudat and Likas, Kota Kinabalu). Like other tribes, their tradition in weaving is also used as traditional clothing for special occasions or festivities.
motif of the pattern
Look at the example of Iranun cloth, you can see that there is a motif of the pattern.
And this motif includes a kind of symmetry that each of the motif rotates 180 degrees around its center, as do the reflections, which have vertical and horizontal reflection axes that connect at a 180-degree rotating center.
In the whole cloth, you will notice that the repeating pattern's symmetry group is a plane crystallographic group of type pmm.
