BARS::39 Miles From Jct. 86 on CA Hwy-78 in California

This road sign is on CA Hwy-78 in California.

```   +----------------------+
| Ocotillo Wells    22 |
| Junction 86       39 |
| Brawley           62 |
+----------------------+
```

To date, MathBabbler has not found any math in this road sign; therefore, he resorted to using the spf(n) function to morph numbers. [The spf(n) function outputs the sum of the prime factors for the input.]

```   the numbers are:  22  39  62  86

the math is:  86 - 22 - 62 = sqrt(sqrt(spf(39)))

observe...
86 - 22 = 64
64 - 62 = 2
spf(39) = 3 + 13 = 16
sqrt(16) = 4
sqrt(4) = 2
```

All four numbers found in this road sign each have only two prime factors.

```   prime_factors(22) = 2 * 11
prime_factors(39) = 3 * 13
prime_factors(62) = 2 * 31
prime_factors(86) = 2 * 43

using the smallest prime factors for each number on the
left-side of the equation and the largest prime factors
for each number on the right-side of the equation...

2 * 3 * 2 * 2 = (13 - 11) * (43 - 31)
```
