%*****************************************************************************80
%
%% EN_R2_11_1 implements the Stroud rule 11.1 for region EN_R2.
%
%  Discussion:
%
%    The rule has order 
%
%      O = ( 4 * N^5 - 20 * N^4 + 140 * N^3 - 130 * N^2 + 96 * N + 15 ) / 15.
%
%    The rule has precision P = 11.
%
%    EN_R2 is the entire N-dimensional space with weight function
%
%      w(x) = exp ( - x1^2 - x2^2 ... - xn^2 ) 
%
%    There are two versions of each rule, chosen by setting the
%    OPTION variable to 1 or 2.
%
%    The rule as tabulated by Stenger is available for N = 2 through 20.
%    This function accepts N = 3 through 5.
