Nazife Özdeş Koca, Mehmet Koca, Ramazan Koç وآخرون · مجلة جامعة السلطان قابوس للعلوم · 2025 · 10.53539/2414-536x.1405

Quasicrystals are obtained as the projections of higher dimensional cubic lattices. This paper aims to show that the affine dihedral subgroup Wa(I2(h)) of the affine group Wa(Bn), h = 2n being the Coxeter number, offers a different perspective to -fold symmetric quasicrystallography. The affine group Wa(I2(h)) is const …

Two Groups 2^3.〖PSL〗_2 (7) and 2^3:〖PSL〗_2 (7) of Order 1344

Mehmet Koca, Ramazan Koç, Nazife Özdeş Koca · مجلة جامعة السلطان قابوس للعلوم · 2019 · 10.24200/squjs.vol24iss1pp57-70

We analyze the group structures of two groups of order 1344 which are respectively non-split and split extensions of the elementary Abelian group of order 8 by its automorphism group 𝑃𝑆𝐿 2 (7).Two groups have the same number of conjugacy classes and the set of dimensions of irreducible representations is equal.The grou …
