In this paper, we study cubic sevenfolds and cubic eightfolds in relation with the Cartan cubic, the E6‐invariant cubic in ℙ26. We prove that a generic cubic sevenfold X can be represented as a linear section of the Cartan cubic by finitely many ways. This allows one to define auto‐equivalences of the non‐commutative Calabi–Yau threefold associated to the generic cubic sevenfold X. Finally, we show that the generic eight‐dimensional section of the Cartan cubic is rational.
