The following are the first few examples of what: (220, 284), (1184, 1210), (2620, 2924), (5020, 5564) & (6232, 6368)?
Amicable numbers period 1. Numbers that are members of an aliquot sequence with period greater than 2 are known as sociable numbers. The smallest pair of amicable numbers is (220, 284). They are amicable because the proper divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55 and 110, of which the sum is 284; and the proper divisors of 284 are 1, 2, 4, 71 and 142, of which the sum is 220. The first ten amicable pairs are: (220, 284), (1184, 1210), (2620, 2924), (5020, 5564), (6232, 6368), (10744, 10856), (12285, 14595), (17296, 18416), (63020, 76084),
WISE 0647-6232 WISE 0647-6232 WISE 0647-6232 (full designation is WISE J064723.23-623235.5) is a nearby brown dwarf of spectral type Y1 ± 0.5, located in constellation Pictor at approximately 28 light-years from Earth. It is one of the two or three reddest and one of the four latest-type brown dwarfs known. WISE 0647-6232 was discovered by Kirkpatrick "et al." from data, collected by Wide-field Infrared Survey Explorer (WISE) Earth-orbiting satellite — NASA infrared-wavelength 40-cm (16-in) space telescope, which mission lasted from December 2009 to February 2011. The discovery was announced in 2013. WISE 0647-6232 was first imaged by WISE on 9 May 2010.
