### We're #3!!

Arxis Technology, Inc. was recently honored as one of the Top 25 IT Firms in the San Fernando Valley by the San Fernando Valley Business Journal. Arxis was #3 on the list, which ranked IT consulting firms in the Greater San Fernando Valley by 2009 revenue totals. We're very proud to be number three and thought you may be interested in the following facts about this special number from Wikipedia:
• Three is the first odd prime number, and the second smallest prime. It is both the first Fermat prime (22n + 1) and the first Mersenne prime (2n − 1), as well as the first lucky prime. However, it's the second Sophie Germain prime, the second Mersenne prime exponent, the second factorial prime (2! + 1), the second Lucas prime, the second Stern prime.
• Three is the first unique prime due to the properties of its reciprocal.
• Three is the aliquot sum of 4.
• Three is the third Heegner number.
• Three is the second triangular number and it is the only prime triangular number. Three is the only prime which is one less than a perfect square. Any other number which is n2 − 1 for some integer n is not prime, since it is (n − 1)(n + 1). This is true for 3 as well, but in its case one of the factors is 1.
• Three non-collinear points determine a plane and a circle.
• Three is the fourth Fibonacci number and the third that is unique. In the Perrin sequence, however, 3 is both the zeroth and third Perrin numbers.
• Three is the fourth open meandric number.
• Vulgar fractions with 3 in the denominator have a single digit repeating sequences in their decimal expansions, (.000..., .333..., .666...)
(Don't worry, mom, we won't dare repeat the vulgar fractions...)
