What caught my eye in this article was,
168 = 180 - 12 = 9(20) - (2)6 = 9(10 + 10) - (1 + 1)6 ---> 911116. 911 inverted on itself.
168 = 42*4 = [40 + (1 + 1)]4 ---> 4114;
168 = 14^2 - 2(14)= (4 + 10)^(1 + 1) - (1 + 1)(14) ---> 41111114.
The latter two expressions average out to 168 ---> 411114. 411 inverted on itself.

The El Paso attack, which left 22 dead, was the third deadliest act of violence by a domestic extremist in more than 50 years. Only the 1995 Oklahoma City bombing, which killed 168 people, and the 2016 Pulse nightclub shooting in Orlando, which killed 49 people, were deadlier.
I looked up a couple other common properties of the number 168.
42*4 = 168 is the number of primes less than 1,000.
42*4 = 168 is the number of hours in a week.
[(41 + 43) - 2]*42^2 = 861 x 168 = 492 x 294.
