We compute the 3-modular character table of the group \(\mathrm{O'N}.2\). Much of the table is deduced character theoretically from the known 3-modular character table of the sporadic simple O’Nan group \(\text {O}'\text {N}\). We finish the remaining questions module theoretically with an application of condensation.
