%C The red field of the Nepalese flag consists of two overlapping triangles:

%C A...D

%C |\ .

%C | \ .

%C | \.

%C | E-F

%C | \.

%C B---C

%C where C and F lie on a vertical line. There is a blue border around this field which makes point F extend slightly further than point C when the entire flag is considered, since angle AFE is smaller than angle ECB. - _Jeremy Tan_, Apr 06 2015

%C This constant is algebraic, specifically quartic. In particular it is the least root of 243356742235044x^4 - 1325568548812608x^3 + 2700899847521244x^2 - 2439951444086880x + 824634725389225. - _Charles R Greathouse IV_, Oct 24 2013

%C Denominator is 4506606337686 = 2 * 3 * 2791 * 13591 * 19801. - _Charles R Greathouse IV_, Jun 16 2020
