Nice one, you just wiped some more numbers.

So let's resume. We eliminated :

All odd exponents : 1, 3, 5, 7, 9, ...

All exponents of the form with odd : 2, 6, 10, 14, 18, 22, ...

All exponents of the form : 2, 4, 8, 16, 32, ...

We're still missing a small - yet infinite - subset of numbers, which can be expressed as , , that is, 12, 24, 36, ...

Am I right ?
