While exploring the idea of measuring one group of things by the same group of things. I came across an interesting example while on a plane trip. In the seat pocket was a holiday book of Australia. In it was a table showing all the airfares from one city to another throughout Australia. this table was a triangular table and all I had to do was duplicate the top right triangle into the lower left. The airfares were keyed in to the nearest $10 (because of field size constraints) as follows and the following grid1803.txt emerged.
