it is a polyhedron that is formed by a regular dodecahedron and 12 irregular uniform pyramids. Whose uniform lateral edges are four times greater or more than four times greater, than each of the uniform edges of the base.

Summary

[edit]
Description
Español: En 1809 el físico y matemático Louis Poinsot publica varios poliedros estrellados de cuales habían sido estudiados y publicados varios siglos antes como poliedros regulares estrellados, por el célebre astrónomo y matemáticos Johannes Kepler. Esta controversia fue solucionada tres años después, en el 1812 por el matemático ingles Arthur Cayley, cuando declaro estos poliedros con el nombre de: poliedros estrellado de Kepler-Poinsot.

El pequeño dodecaedro de Cayley: es un poliedro que está formado por un dodecaedro regular y 12 pirámides uniformes irregulares, cuyas aristas laterales uniformes son cuatros veces mayores o más de cuatros veces mayores, que cada una de las aristas uniformes de la base. La medida que poseen cada una de las pirámides (PV3), para la construcción del pequeño dodecaedro estrellado ampliado de Cayley, es que todas las aristas laterales de las pirámides pentagonales son iguales a (xy), y todas las aristas de la base de las pirámides pentagonales son iguales (x). Siendo (y) un numero entero positivo igual o mayor que cuatro y ≥ 4, siendo (x) un número entero igual o mayor que uno (x ≥ 1). El pequeño dodecaedro de Cayley, en el conjunto de los poliedros que están formados por caras de formas triangulares, ocupa la posición # 29 (L=29, A=3L+3, V=L+3 y C=2L+2), de acuerdo a las fórmulas de las sucesiones poliédricas triangulares.

La tercera variación del pequeño dodecaedro estrellado, fue nombrada el 22 de noviembre del 2012 con el nombre de pequeño dodecaedro de Cayley, por el autodidacta dominicano Jose Joel Leonardo, consagrado a la memoria del eximio matemático británico Arthur Cayley.
English: In 1809 the physicist and mathematician Louis Poinsot publishes several star polyhedra of which they had been studied and published several centuries before as regular star polyhedra, by the famous astronomer and mathematicians Johannes Kepler. This controversy was resolved three years later, in 1812 by the English mathematician Arthur Cayley, when I declare these polyhedra with the name of: Kepler-Poinsot star polyhedra.

Cayley's little dodecahedron: it is a polyhedron that is formed by a regular dodecahedron and 12 irregular uniform pyramids. Whose uniform lateral edges are four times greater or more than four times greater, than each of the uniform edges of the base. The measure that each of the pyramids (PV3) possesses, for the construction of the small expanded starry dodecahedron of Cayley, is that all the side edges of the pentagonal pyramids are equal to (xy), and all the edges of the base of the pentagonal pyramids are equal (x). Being (y) a positive integer equal to or greater than four and ≥ 4, (x) being an integer equal to or greater than one (x ≥ 1).

Cayley's little dodecahedron, in the set of polyhedra that are formed by faces of triangular shapes, occupies the position # 29 (L = 29, A = 3L + 3, V = L + 3 and C = 2L + 2), according to the formulas of triangular polyhedral successions.

The third variation of the little dodecahedron was named on November 22, 2012 with the name of Cayley's little dodecahedron, by the self-taught Dominican Jose Joel Leonardo, consecrated to the memory of the excellent British mathematical Arthur Arthur Cayley.

Cette controverse a été résolue trois ans plus tard, en 1812, par le mathématicien anglais Arthur Cayley, lorsque j'ai déclaré ces polyèdres avec le nom de: Kepler-Poinsot star polyhedra.

Le petit dodécaèdre de Cayley: c'est un polyèdre formé par un dodécaèdre régulier et 12 pyramides uniformes irrégulières. Dont les bords latéraux uniformes sont quatre fois supérieurs ou plus de quatre fois plus grands que chacun des bords uniformes de la base. La mesure que possède chacune des pyramides (PV3), pour la construction du petit dodécaèdre étoilé élargi de Cayley, est que tous les bords latéraux des pyramides pentagonales sont égaux à (xy), et tous les bords de la base de la les pyramides pentagonales sont égales (x). Être (y) un entier positif égal ou supérieur à quatre et ≥ 4, (x) étant un entier égal ou supérieur à un (x ≥ 1).

Le petit dodécaèdre de Cayley, dans l'ensemble des polyèdres formés par des faces de formes triangulaires, occupe la position # 29 (L = 29, A = 3L + 3, V = L + 3 et C = 2L + 2), selon les formules de successions polyédriques triangulaires.

La troisième variante du petit dodécaèdre écrasé a été nommée le 22 novembre 2012 avec le nom du petit dodécaèdre de Cayde, par l'autodidacte dominicain Jose Joel Leonardo, consacré à la mémoire de l'excellent mathématique britannique Arthur Arthur Cayley.
