62 (number)
62 (sixty-two) is a natural number following 61 and preceding 63. == In mathematics == 62 is a composite number with the divisors 2 and 31, being the eighteenth discrete semiprime. It has an aliquot sum of 34; itself a discrete semiprime, and the 10 member aliquot sequence (62,34,20,22,14,10,8,7,1,0). 62 is therefore the tenth member of the 7-aliquot tree. 62 is a nontotient. It is the sum of the number of faces, edges and vertices of icosahedron or dodecahedron; and the number of faces of two of the Archimedean solids, the rhombicosidodecahedron and truncated icosidodecahedron. 62 is a repdigit in base 5 (222). In base 10, 62 is also the only number whose cube (238328) consists of 3 digits each occurring 2 times.〔(【引用サイトリンク】url=http://www.johndcook.com/blog/2010/02/05/carnival-of-mathematics-62/ )〕
