72 is the mid point between 55 and 89 and one of the numbers I use in fx Bar Counts. While the Lucas number in the fibo ratio series is 76, 72 like 36 is a product of Lucas number 18 and both are significant as a trend change can occur at those BC. Note the Fibonacci BC on the Monthly.
Coincidentally '72' is where gold has currently topped out -- $720s, hitting the 76.4% Retracement of the all-time high.
