# --description--
The smallest positive integer $n$ for which the numbers $n^2 + 1$, $n^2 + 3$, $n^2 + 7$, $n^2 + 9$, $n^2 + 13$, and $n^2 + 27$ are consecutive primes is 10. The sum of all such integers $n$ below one-million is 1242490.
What is the sum of all such integers $n$ below 150 million?
# --hints--
`primePattern()` should return `676333270`.
```js
assert.strictEqual(primePattern(), 676333270);
```
# --seed--
## --seed-contents--
```js
function primePattern() {
return true;
}
primePattern();
```
# --solutions--
```js
// solution required
```
