	Amicable Numbers by Shyam Sunder Gupta
		The numbers 220 and 284 form the smallest pair of amicable numbers (also known as friendly numbers) known to Pythagoras.
		Two numbers are called Amicable (or friendly) if each equals to the sum of the aliquot divisors of the other (aliquot divisors means all the divisors excluding the number itself).
		Harshad (or Niven) numbers are those numbers which are divisible by their sum of the digits.

		During the period that the Commission was reaffirming the 40-mile rule for 220 MHz Service, the Commission began examining the need for certain loading and performance require ments in light of the CMRS regulatory framework and the Commission's authority to use com petitive bidding to choose from among mutually exclusive applications.
		The Commission concluded that no change to the 220 MHz rules was required in the CMRS proceeding to ensure regulatory symmetry and stated that it intended to initiate a separate proceeding to address future licensing and service rules for the 220 MHz Service.
		With respect to Phase II licenses, the Commission has not limited the number of licenses that may be acquired by one entity, and the Commission allows licensees to place stations anywhere within a licensee's geographically licensed area.

		The 95% confidence intervals were calculated by multiplying the standard errors of the coefficients with the t-value for the appropriate number of degrees of freedom (Youden 1951, table 1).
		This significantly limited the number of experimental points available for corrosion rate determinations, from as low as two test coupons each at two exposure times (all materials in run 5) to at most two test coupons each after six exposure times.
		This would increase the number of experimental points available for the rate determination significantly and could be expected to narrow the confidence interval for the calculated rate.

		In April 2002, we moved to the major number 220 which had been previously reserved for Myrinet devices (or now less specifically to message passing technology devices).
		GM scripts started to use major number 220 at that time, but we also kept backwards compatibility in the driver for major number 41 to allow a smoother transition.
		Starting with gm-2.0.15, and in the case of Linux 2.6 kernels, we dropped the support for the obsolete major number 41 when introducing the support for udev/sysfs.
