%N Divisors of 180.
%C These divisors represent a special case of the "nice angles" discussed at the Geometry Center when bending generating triangles to construct polyhedra (link given below). - _Alford Arnold_, Apr 16 2000
%C 180 is a highly composite number: A002182(11) = 180. - _Reinhard Zumkeller_, Jun 21 2010
%C There are 752 ways to partition 180 as a sum of some of its distinct divisors (see A033630). This is more than any smaller number (hence 180 is listed in A065218). - _Alonso del Arte_, Sep 20 2017
