BARS::63 Miles To I-40 on Indian Highway-371 in New Mexico

This road sign is on southbound Indian Highway-371 in New Mexico.

The road sign says...

+--------------------+
| Crownpoint      42 |
| Thoreau         61 |
| I-40            63 |
+--------------------+
   the numbers are:  42  61  40  63

   the math is:  42 + 61 - 63 = 40

   more math:  (61 + 63) % 42 = 40

   rsAgeEval:  sqrt(61 * (63 + 40 - 42)) = 61
   * RoadHacker was 61 years young when he found this road sign.

   rs42Eval:  sqrt(42^(sqrt((61 + 63) % 40))) = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rsCardinalityEval:  42 - 61 + 63 - 40 = 4
   * There are four numbers in this road sign.

   * spf(n) = the sum of the prime factors of n
     domain: n must be a composite number
   * 40 is composite; spf(40) = 2+2+2+5 = 11
   * 42 is composite; spf(42) = 2+3+7 = 12
   * 61 is prime; spf(61) = domain error
   * 63 is composite; spf(63) = 3+3+7 = 13

   * reverse_digits(n) = the digits of n reversed
     domain:  n must be a prime number
   * 61 is prime; reverse_digits(61) = 16

   BARSfunc math:  spf(42) + sqrt(spf(42) + spf(63)) = reverse_digits(61)
