It is shown that the mod 3 cohomology of a 1‐connected, homotopy associative mod 3 H ‐space that is rationally equivalent to the Lie group E 6 is isomorphic to that of E 6 as an algebra. Moreover, it is shown that the mod 3 cohomology of a nilpotent, homotopy‐associative mod 3 H ‐space that is rationally equivalent to E 6 , and whose fundamental group localized at 3 is non‐trivial, is isomorphic to that of the Lie group Ad E 6 as a Hopf algebra over the mod 3 Steenrod algebra. It is also shown that the mod 3 cohomology of the universal cover of such an H ‐space is isomorphic to that of E 6 as a Hopf algebra over the mod 3 Steenrod algebra. 2000 Mathematics Subject Classification 57T05, 57T10, 57T25.
