Regarding subsets containing three points A, B, C (Figure 5), according to the nature of FSMT, we can see that constructing FSMT for A, B, C is equal to finding a Steiner point P, which makes PA + PB + PC minimum and requires [angle]APB = [angle]BPC = [angle]APC = [angle]120[degrees].
It can be proved that the length of the FSMT is equal to the length of the line-segment C[E.sub.1] recorded as L([F.sub.S]).
The terminal D [member of] [R.sub.k]\C([E.sub.1], C, [E.sub.2]) yields an FSMT. More precisely, the intersection of the line segment D[E.sub.2] with arc [E.sub.1]C is the location of Q.
FSMT for A, B, C, D is obtained with connecting AP, BP, PQ, CQ, DQ.
