The notion of a building was invented by Jacques Tits as a means of describing simple algebraic groups over an arbitrary field. Tits demonstrated how to every such groupG one can associate a simplicial complex Δ=Δ(G) with an action of G, called the spherical building of G. The group G imposes very strong combinatorial regularity conditions on the complexes Δ that can arise in this fashion. By treating these conditions as axioms for a class of simplicial complexes, Tits arrived at his first definition of a building. A part of the data defining a building Δ is a Coxeter groupW, which determines a highly symmetrical simplicial complex Σ=Σ(W,S), called the Coxeter complex. A building Δ is glued together from multiple copies of Σ, called its apartments, in a certain regular fashion. When W is a finite Coxeter group, the Coxeter complex is a topological sphere, and the corresponding buildings are said to be of spherical type. When W is an affine Weyl group, the Coxeter complex is a subdivision of the affine plane and one speaks of affine, or Euclidean, buildings. An affine building of type is the same as an infinite tree without terminal vertices.
Online creation, also referred to as OLC, online coding, online building, and online editing, is a software feature of MUDs that allows users to edit a virtual world from within the game itself. In the absence of online creation, content is created in a text editor or level editor, and the program generally requires a restart in order to implement the changes.
Online creation as original content
An aspect of online creation that separates it from "mere game play" is that online creation systems can generally be used to create new content— new objects, new locations, new creatures — rather than simply creating instances of predefined items in the game world. Some have observed that certain forms of online creation — notably those associated with creating new commands — can threaten the stability of the server.
The first publicly available MUD that featured in-game creation of the game world was Skrenta's 1988 Monster.
Baggage cannot be checked at this location; however, up to two suitcases in addition to any "personal items" such as briefcases, purses, laptop bags, and infant equipment are allowed on board as carry-ons.
This is at least the fourth station along the Grand Trunk Western Railroad (GTW) line through Flint. The railroad arrived from Port Huron in 1871 and originally a wooden structure served as the passenger station. A 1905 stone and brick station was moved to Muskegon in 1927. The third GTW depot, located at 120 East 14th Street, was used by Amtrak until 1989 and demolished thereafter. The current station on Dort Highway provides easy access to I-69.
The Flint River is a 344-mile-long (554km) river in the U.S. state of Georgia. The river drains 8,460 square miles (21,900km2) of western Georgia, flowing south from the upper Piedmont region south of Atlanta to the wetlands of the Gulf Coastal Plain in the southwestern corner of the state. Along with the Apalachicola and the Chattahoochee rivers, it forms part of the ACF basin. In its upper course through the red hills of the Piedmont, it is considered especially scenic, flowing unimpeded for over 200 miles (320km).
