Recently I realized the special properties of following numbers:
It is the only number which is both real and purely imaginary at same time.
It is sufficient to create all the counting numbers (a.k.a. natural numbers).
This is the maximum exponent, , for which has solution in natural numbers. This peculiar property leads to “Fermat’s Last Theorem”.
If you also have some special numbers in mind, please do share them below as comments.
