To clarify for other than Charles and Ben, unit 1 is centre to centre. 
Each regular hexagon has six equilateral triangles, and each height is 1/2,
so each hexagon side is 1/root-3 by 30-60-90 triangle. That makes each
orthogonal step in hexagons the 1.0 and each diagonal step 3/root-3 seen by
inspection and counting.

[Examples with even SOLL irrelevantly: (0,10) and (5,5) have same LL and SOLL 10 and 100; also (0,12) and (6,6); also (0,6) and (3,3)]

What would be second case with odd SOLL? Many, (2,3) of 31 SOLL for one.
