  In this work, we investigated resonant production of spin-3/2 color octet
electron at the Large Hadron electron Collider (LHeC). Signal and background
analysis have been performed and discovery, observation and exclusion limits
are determined for spin 3/2 color octet electron masses. Reachable values of
the compositeness scale are presented as a function of the spin-3/2 color octet
electron masses.
