We report a quantum oscillation study in the Dirac nodal-line semimetal candidate <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"> <a:msub> <a:mi>TaPtTe</a:mi> <a:mn>5</a:mn> </a:msub> </a:math> . The Fermi surface is probed via magnetic torque measurements with the magnetic field applied in the crystallographic <b:math xmlns:b="http://www.w3.org/1998/Math/MathML"> <b:mrow> <b:mi>a</b:mi> <b:mtext>−</b:mtext> <b:mi>b</b:mi> </b:mrow> </b:math> and <c:math xmlns:c="http://www.w3.org/1998/Math/MathML"> <c:mrow> <c:mi>b</c:mi> <c:mtext>−</c:mtext> <c:mi>c</c:mi> </c:mrow> </c:math> planes. The experimentally determined de Haas–van Alphen frequencies are consistent with results from band-structure calculations. This study serves as an extension to the scarce quantum oscillation data on <d:math xmlns:d="http://www.w3.org/1998/Math/MathML"> <d:msub> <d:mi>TaPtTe</d:mi> <d:mn>5</d:mn> </d:msub> </d:math> currently present in the literature.
