You have to solve the following:

\(0\) *_ \(0\) _* \(0 = 6\)

\(1\) *_ \(1\) _* \(1 = 6\)

\(2\) *_ \(2\) _* \(2 = 6\)

\(3\) *_ \(3\) _* \(3 = 6\)

\(4\) *_ \(4\) _* \(4 = 6\)

\(5\) *_ \(5\) _* \(5 = 6\)

\(6\) *_ \(6\) _* \(6 = 6\)

\(7\) *_ \(7\) _* \(7 = 6\)

\(8\) *_ \(8\) _* \(8 = 6\)

\(9\) *_ \(9\) _* \(9 = 6\)

You can put as many operations in the spaces but they must not contain a digit/letter. e.g.

You can have \(2 \times \sqrt{2} + 2!\) but not \(2^2 + \sqrt [3]{2} + 2e\).

You can only use factorials and double factorials, BODMAS/PEMDAS operations and square roots.

Good luck.

**Extension**: Find the smallest positive integral value of \(n\) such that \(n\) *_ \(n\) _* \(n = 6\) has no solutions.

Ahh... but that was only the first part o the problem. You have to find as many different solutions as you can.
