The earliest study of groups as such probably goes back to the work of Lagrange in the late 18th century. However, this work was somewhat isolated, and 1846 publications of Augustin Louis Cauchy and Galois are more commonly referred to as the beginning of group theory. The theory did not develop in a vacuum, and so three important threads in its pre-history are developed here. WebDepending on the value of n, the group D(n;n;n) can be generated by orientation{preserving transformations of a tiling T n of a constant curvature surface (denoted, from now on, by the symbol S) by regular triangles.
