New Zealand landline phone numbers have a total of eight digits, excluding the leading 0: a one-digit area code, and a seven-digit phone number (e.g. 09 700 1234), beginning with a digit between 2 and 9 (but excluding 900, 911, and 999 due to misdial guards). There are five regional area codes: 3, 4, 6, 7, and 9.
Since the greatest prime factor of 44 2 + 1 = 1937 is 149 and thus more than 44 twice, 44 is a Størmer number. [3] Given Euler's totient function , φ(44) = 20 and φ(69) = 44. 44 is a tribonacci number , preceded by 7, 13, and 24, whose sum it equals.
In the city of São Paulo, although the area code has two digits, there were still six-digit telephones in use; 3X-nnnn phone numbers (with X=4-7) changed to 60X-nnnn and then to 310X-nnnn, 9X-nnnn phone numbers (with X=2 or 3) changed to 69X-nnnn and then to 669X-nnnn (today 269X-nnnn), and 6n-nnnn phone numbers which were changed directly to ...
The top 4 numbers are available across areas. Following numbers may be valid for Minsk only and may not exist or have a different short number in other areas. Some of these numbers were formed by changing from old 2-digit codes to 3 by adding leading 1 or by replacing 0 with 1 in the old 3-digit code. 101 and 112 – Fire brigade 102 – Police
The Mersenne Twister is a general-purpose pseudorandom number generator (PRNG) developed in 1997 by Makoto Matsumoto (松本 眞) and Takuji Nishimura (西村 拓士). [1] [2] Its name derives from the choice of a Mersenne prime as its period length.
A USB-pluggable hardware true random number generator. In computing, a hardware random number generator (HRNG), true random number generator (TRNG), non-deterministic random bit generator (NRBG), [1] or physical random number generator [2] [3] is a device that generates random numbers from a physical process capable of producing entropy (in other words, the device always has access to a ...
43 is the smallest prime number expressible as the sum of 2, 3, 4, or 5 different primes: 43 = 41 + 2; 43 = 11 + 13 + 19; 43 = 2 + 11 + 13 + 17; 43 = 3 + 5 + 7 + 11 + 17. 43 is the smallest number with the property 43 = 4*prime(4) + 3*prime(3). Where prime(n) is the n-th prime number. There are only two numbers with that property, the other one ...
From fixed line or mobile phone: 19XX + 00 + 1 + area code + phone number From mobile phone (2° alternative): +1 + area code + phone number (your call will go through your usual provider's network) Special numbers
