Another funny thing is that the fundamental identity satisfied by $\sigma$ holds and looks exactly the same for $p$-adics if one defines the norm of a vector in $\mathbb{Q}_p^d$ by $\|x\|=\max_i|x_i|_p$, and unit sphere inversion by $\sigma(x)=\|x\|^{2}x$. The $+2$ instead of $-2$ as exponent is not a typo. This is elaborated upon in my youtube talk mentioned in my answer. | |

Correct the hyperbolic metric which I copied and pasted without thinking before...
