b great little

There are 1616 "Littles" and 1102 "Greats" in the map below.

There are 1230 "Littles" and 1077 "Greats" in the map below.

The diagram below shows the differences between the eastings and between the northings of the places

with names beginning "Great" and "Little". The bins of the histograms are 1 km wide.

The RMS separation is about 1.32 km. The accuracy is limited by the fact that the OS data are truncated

so that each position is centred in a 1 km square of the OS map. The circles in the diagram have had a

random amount with a range of +- 0.5 km added to their coordinates to break the degeneracy.
