‎There are a few finite groups that are determined up to isomorphism solely by their order, such as $mathbb{Z}_{2}$ or $mathbb{Z}_{15}$. Still other finite groups are determined by their order together with other data, such as the number of elements of each order, the structure of the prime graph, the number of order components, the number of Sylow $p$-subgroups for each prime $p$, etc. In this...

a fullerene graph is a 3−connected planar graph whose faces are pentagons and hexagons.the clar number of a fullerene is the maximum size of sextet patterns, the sets of disjointhexagons which are all m-alternating for a kekulé structure m of f. an exact formula of clarnumber of some fullerene graphs and a class of carbon nanocones are obtained in this paper.

conclusion a significant relationship exists between the type of facial skeletal classification and the shape of the sella turcica; as in class iii patients, sella turcica bridge was reported with a higher frequency. also, sella turcica had a significantly higher length in these patients than in those with class i and class ii facial skeletal types. results sella turcica had normal morphology i...
