The committee debated the possibility of a shift function (like in ITA2), which would allow more than 64 codes to be represented by a six-bit code. In a shifted code, some character codes determine choices between options for the following character codes. It allows compact encoding, but is less reliable for data transmission as an error in transmitting the shift code typically makes a long part of the transmission unreadable. The standards committee decided against shifting, and so ASCII required at least a seven-bit code.:215, 236 § 4
Why did they decide against shifting code?

Notre Dame's conference affiliations for all of its sports except football and fencing changed in July 2013 as a result of major conference realignment, and its fencing affiliation will change in July 2014. The Irish left the Big East for the ACC during a prolonged period of instability in the Big East; while they maintain their football independence, they have committed to play five games per season against ACC opponents. In ice hockey, the Irish were forced to find a new conference home after the Big Ten Conference's decision to add the sport in 2013–14 led to a cascade of conference moves that culminated in the dissolution of the school's former hockey home, the Central Collegiate Hockey Association, after the 2012–13 season. Notre Dame moved its hockey team to Hockey East. After Notre Dame joined the ACC, the conference announced it would add fencing as a sponsored sport beginning in the 2014–15 school year. There are many theories behind the adoption of the athletics moniker but it is known that the Fighting Irish name was used in the early 1920s with respect to the football team and was popularized by alumnus Francis Wallace in his New York Daily News columns. The official colors of Notre Dame are Navy Blue and Gold Rush which are worn in competition by its athletic teams. In addition, the color green is often worn because of the Fighting Irish nickname. The Notre Dame Leprechaun is the mascot of the athletic teams. Created by Theodore W. Drake in 1964, the leprechaun was first used on the football pocket schedule and later on the football program covers. The leprechaun was featured on the cover of Time in November 1964 and gained national exposure.
