Certain connect sums of torus knots with infinitely many non-characterizing slopes

For a knot $K,$ a slope $r$ is said to be characterizing if for no other knot $J$ does $r$-framed surgery along $J$ yield the same manifold as $r$-framed surgery on $K\mathrm{.}$ Applying a condition of Baker and Motegi, we show that the knots $T_{2,2n+3}\mathrm{\#}{T}_{-2,2n+1}$ have infinitely many non-characterizing slopes.
