The group action is sharply 2-transitive if such is unique. A 2-transitive group is a group such that there exists a group action that's 2-transitive and faithful. Similarly we can define sharply 2-transitive group.
Satellite image of the Tibetan Plateau between the Himalayan mountains to the south and the Taklamakan Desert to the north. In geology and physical geography, a plateau (/ p l ə ˈ t oʊ, p l æ ˈ t oʊ, ˈ p l æ t oʊ /; French:; pl.: plateaus or plateaux), [1] [2] also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the ...
A unit of area traditionally defined as the area of a plot of land one chain (66 feet) by one furlong (660 feet), equivalent to 43,560 square feet (0.001563 sq mi; 4,047 m 2), or about 0.40 hectare. active volcano A volcano that is currently erupting, or one that has erupted within the last 10,000 years (the Holocene) or during recorded history ...
The cyclic group C 3 consisting of the rotations by 0°, 120° and 240° acts on the set of the three vertices.. In mathematics, a group action of a group G on a set S is a group homomorphism from G to some group (under function composition) of functions from S to itself.
Curvature of Riemannian manifolds of dimension at least two can be defined intrinsically without reference to a larger space. For curves, the canonical example is that of a circle, which has a curvature equal to the reciprocal of its radius. Smaller circles bend more sharply, and hence have higher curvature.
In the presence of astigmatism, an off-axis point on the object is not sharply imaged by the optical system. Instead, sharp lines are formed at the tangential and sagittal foci. The image at the tangent focus is a short line, oriented in the direction of the sagittal plane; images of circles centered on the optic axis, or small lines tangential ...
1. A space between the threads of a net, e.g. that part of a leaf surface defined by each of the elements of a vein network; as with cacti, the area between the veinlets of a leaf. 2. A structure on the stem node of a cactus, morphologically a specialised branch; the region of a cactus upon which spine s, glochid s, and flowers are borne. aril
