X(2209) lies on these lines:
1,1258 6,31 8,238 41,904 69,2239 86,750 100,1740 560,692 604,1911 869,2300 941,2344 2175,2210X(2209) = X(32)-Ceva conjugate of X(31)
X(2209) = X(2176)-cross conjugate of X(31)
X(2209) = crosspoint of X(I) and X(J) for these I,J: 692 1403,2176
X(2209) = crosssum of X(244) and X(693)
