BARS::64 Miles From McLean, Illinois

This road sign is on eastbound US Highway-136 in Illinois.

The road sign says...

   +---------------+
   | Havana     16 |
   | McLean     64 |
   +---------------+
   the numbers are:  16  64

   the math is:  sqrt(16) = cuberoot(64)

   more math:  sqrt(sqrt(16)) = cuberoot(sqrt(64))

   rsCardinalityEval:  sqrt(64 / 16) = 2
   number system rsCardinalityEval:  log(6416) = 2
   * There are two numbers in this road sign.

   off-by-one rsStateEval:  spf(16) + spf(64) = 21-1
   * Illinois was the 21st state admitted to the Union.
   * spf(n) = the sum of the prime factors of n
     domain: n must be a composite number
   * 16 is composite; spf(16) = 2+2+2+2 = 8
   * 64 is composite; spf(64) = 2+2+2+2+2+2 = 12
