\subsubsection{The Htt coupling}  As mentioned in Section~\ref{sec:ee500}, a centre-of-mass energy of 500 GeV cannot compete with the HL-LHC for the Htt coupling measurement. To reach an accuracy in $\epem$ collisions similar to the HL-LHC (less than 5\%), the upgrade of either ILC up to $\sqrt{s}=1$~TeV or CLIC up to $\sqrt{s}=3$~TeV is needed. A precision of 4\% on the Htt coupling would be achieved with an integrated luminosity of 1~$\inab$ (ILC-1000) or 2~$\inab$ (CLIC). On the other hand, an integrated luminosity of 3~$\inab$ with pp collisions either at the HE-LHC or the VHE-LHC would allow the precision on the Htt coupling to be significantly reduced improved  to a couple of per-cent or a fraction of a per-cent, respectively. \subsubsection{The HHH coupling}
