Lowell_: Regular polygons with n sides in which internal angles have integral number of degrees (n >= 3). %C A018412 360 is a highly composite number: A002182(13) = 360. - _Reinhard Zumkeller_, Jun 21 2010 %C A018412 There are 22209 ways to represent 360 as a sum of its distinct divisors (A033630). That's more than any smaller number, hence 360 is in A065218. - _Alonso del Arte_, Oct 09 2017 %H A018412 <a href="/index/Di#divisors">Index entries for sequences related to divisors of numbers</a> %t A018412 Divisors[360] (* _Vladimir Joseph Stephan Orlovsky_, Feb 21 2012 *) %o A018412 (PARI) divisors(360) \\ _Charles R Greathouse IV_, Jun 21 2017 %Y A018412 Cf.
