In recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same. The order of the magic square is the number of integers along one side (n), and the constant sum is called the magic constant. If the array includes just the positive integers , the magic square is said to be normal. Some authors take magic square to mean normal magic square.

The Convair 880 is an American narrow-body jet airliner produced by the Convair division of General Dynamics. It was designed to compete with the Boeing 707 and Douglas DC-8 by being smaller but faster, a niche that failed to create demand. When it was first introduced, some in aviation circles claimed that at 615 mph (990 km/h), it was the fastest jet transport in the world. Only 65 Convair 880s were produced over the lifetime of the production run from 1959 to 1962, and General Dynamics eventually withdrew from the airliner market after considering the 880 project a failure. The Convair 990 Coronado was a stretched and faster variant of the 880.

Pacific Commons is a master-planned, mixed-use development consisting of 840 acres in Fremont, California currently in development by Catellus Development Corporation. It sits on part of the site of what was once the Fremont Dragstrip/Baylands Raceway Park and the Sky Sailing Airport, a glider field. Given Fremont's location at the Northern tip of Silicon Valley, Catellus originally planned the development to house primarily high-tech research and development operations with a moderate amount of retail and restaurant space, a convention center, and a hotel. Until the dot-com bubble, Cisco Systems had planned to relocate its headquarters to Pacific Commons and consolidate substantially all of its San Francisco Bay Area operations to a large campus in Pacific Commons, which would have consisted of several high-rise office buildings. With the downturn in the technology industry, however, Cisco put its plans on hold. While it is unclear whether Cisco will ultimately relocate its headquarters to Fremont, in 2011 Cisco purchased 149 acres of vacant land in Fremont, most of it from Catellus, fueling speculation that, at some point, it will move forward with its headquarters move to Pacific Commons.
