BARS::Southbound US Hwy-191 South of Safford, Arizona

This road sign is on southbound palindromic prime numbered US Hwy-191 just south of Safford, Arizona.

The road sign says...

   +-----------------------+
   | Jct SR 366          4 |
   | Jct I-10           30 |
   | Willcox            42 |
   +-----------------------+
   the numbers are:  366  4  10  30  42

   the math is:  spf(366) = 42 + 30 - 10 + 4

   observe...  prime factors of 366 are:  2, 3, 61

   This road sign was found on US Hwy-191.

   RSeval:  366 / 102 + (42 - 30 - 4) = 191  

   observe...
      102 = 2         [i.e. binary 10 equals decimal 2]
      366 / 2 = 183
      42 - 30 - 4 = 8
      183 - 8 = 191   

   [solve for spf(366)]  42 + 30 - spf(366) = 10 - 4

Note: SR (State Route) 366 provides access to the Mount Graham International Observatory located on top of Mount Graham.
