BARS::196 Miles From San Diego, California, on I-8 in Arizona

This road sign is on westbound I-8 in Arizona.

The road sign says...

   +---------------------+
   | Foothills Blvd    5 |
   | Yuma             19 |
   | San Diego       196 |
   +---------------------+
   the numbers are:  5  19  196

   the math is:  19 - 5 = sqrt(196)

   off-by-one rsCardinalityEval:  sqrt(196 - summation(5, 19)) = 3+1
   off-by-one rsCardinalityEval:  sqrt(sqrt(196 - summation(5, 19))) = 3-1
   off-by-one rsCardinalityEval:  cuberoot(sqrt(196) - (5! % 19)) = 3-1
   * There are three numbers in this road sign.
   * summation(5, 19) = 5+6+7+...+17+18+19 = 180

   off-by-one rs37Eval:  5 + 19 + sqrt(196) = 37+1
   off-by-one rs37Eval:  (19 % 5)! + sqrt(196) = 37+1
   * Why rs37Eval? 37 Heaven @ http://thirty-seven.org

   off-by-one rsAgeEval:  196 - 5! - 19 = 56+1
   * RoadHacker was 56 years young when he found this road sign.

   BARSfunc math:  mult_digits(19) + 5 = sqrt(196)
   * mult_digits(n) = product of the digits of n
     domain:  n must be a prime number
   * 19 is prime; mult_digits(19) = 1*9 = 9
Update::2015.08.30

This BARS was updated after MathBabbler found out that the number 196 was the smallest Lychrel Number.

   the numbers are:  5  19  196

   rsHwyEval:  sqrt(196) - 5! % 19 = 8
   off-by-one rsHwyEval:  sqrt(196) / sqrt(factorial-1(5 + 19)) = 8-1
   * This road sign is on I-8.

   off-by-one rsAgeEval:  196 - 5! - 19 = 58-1
   * MathBabbler was 58 years young when he updated this BARS.

Note: This was MathBabbler's 800th BARS (BAB# 3774).
