"And they stood two years without a gaon; after this Mar Rav Kohen Tzedek bar Mar Rav Ivumi the gaon was installed, ten and a half years" — placed c. 832–843 CE in the standard rosters.
The Iggeret gives tenure lengths without absolute anchors for Sura's geonim; CE anchoring follows the Sura Academy roster.
