I have a whole section on triples to upload shortly but I can cut this bit out for the purpose of illustration.

"These triples (222, 444, 888, etc) appear to be quite common to Greek measure and the larger the structure the more likely they are of being detected. The Greek stadium, for example, which is of a different construction (to temples) and which made use of the long cubit often employed triple numbers. The rectangular stadium of Aphrodisias in Turkey was set out 262m long and 59m wide which converts to:"

500 long cubits of 20.625 inches = 10312.5 inches = 261.9375m (262m)
500 long cubits of 20.625 inches /4.44 = 2322.635.. inches = 58.9949m (59m)

I refer you to Legon's royal cubit and my royal cubit both based on Petrie's royal cubit (which is the long cubit of the ancient world)

20.620 +/- .005 inches.

Then there is the 250 cubit number (1/2 of that above) which Kanga proposed as being significant..
