BARS::94 Miles From Phoenix on AZ Hwy-85 in Arizona

This road sign is on northbound AZ Hwy-85 in Arizona.

The road sign says...

   +-----------------+
   | Gila Bend    29 |
   | Phoenix      94 |
   +-----------------+
   the numbers are:  29  94

   BARSfunc rsCardinalityEval:  94 - reverse_digits(29) = 2
   * There are two numbers in this road sign.
   * reverse_digits(n) = the digits of n reversed
     domain:  n must be a prime number
   * 29 is a prime number; reverse_digits(29) = 92

   BARSfunc rsCardinalityEval:  
   ... spf(spf(94)) % cuberoot(spf(reverse_digits(29))) = 2
   * There are two numbers in this road sign.
   * spf(n) = the sum of the prime factors of n
   * spf(94) = 2+47 = 49; spf(49) = 7+7 = 14
   * spf(92) = 2+2+23 = 27

   BARSfunc off-by-one rs42Eval:  29 + spf(spf(94)) = 42+1
   * 42 is the "Answer to Life, the Universe, and Everything"
