94 (number)

94 (ninety-four) is the natural number following 93 and preceding 95.

In mathematics

94 is:

• the twenty-ninth distinct semiprime and the fourteenth of the form (2.q).
• the ninth composite number in the 43-aliquot tree. The aliquot sum of 94 is 50 within the aliquot sequence; (94,50,43,1,0).
• the second number in the third triplet of three consecutive distinct semiprimes, 93, 94 and 95
• a 17-gonal number and a nontotient.
• an Erdős–Woods number, since it is possible to find sequences of 94 consecutive integers such that each inner member shares a factor with either the first or the last member.
• a Smith number in decimal.

In computing

The ASCII character set (and, more generally, ISO 646) contains exactly 94 graphic non-whitespace characters, which form a contiguous range of code points. These codes (0x21–0x7E, as corresponding high bit set bytes 0xA1–0xFE) also used in various multi-byte encoding schemes for languages of East Asia, such as ISO 2022, EUC and GB 2312. For this reason, code pages of 94² and even 94³ code points were common in East Asia in 1980s–1990s.

In other fields

94 is:

• Used as a nonsense number by the British satire magazine Private Eye. Most commonly used in spoof articles end halfway through a sentence with "(continued p. 94)". The magazine never extends to 94 pages: this was originally a reference to the enormous size of some Sunday newspapers.
• The international calling code for Sri Lanka
