In Parshas Eikev (Devarim 11:6), Moshe recounts the results of the dispute between Korach and Moshe, namely the ground opening its mouth and swallowing them up. There is one significant person missing from the list - Korach. Doson and Aviram, who joined Korach, are mentioned, but Korach is left out.
Why is Korach, who initiated the whole confrontation, not mentioned as having been swallowed up?
The answer doesn't seem to be related to whether or not Korach was alive when he was swallowed up, as the above cited verse does not say anything about that group being swallowed up alive. The answer does not seem to be that Korach was not swallowed up, because Bamidbar 26:10 says (as understood by one opinion in Sanhedrin 110) that Korach was swallowed up.
