We study the radius RT​ of a self-repellent fractional Brownian motion
{BtH​}0≤t≤T​ taking values in Rd. Our
sharpest result is for d=1, where we find that with high probability,
\begin{equation*}
R_T \asymp T^\nu, \quad \text{with ν=32​(1+H).}
\end{equation*} For d>1, we provide upper and lower bounds for the exponent
ν, but these bounds do not match
