If this Witt index is finite, then X is the Tits quadrangle arising from the corresponding building of type B_m or D_m by a standard construction.</p> </div> </div> </div>}, journal={New Zealand Journal of Mathematics}, author={Mühlherr, Bernhard and Weiss, Richard}, year={2021}, month={Sep.}, pages={427–452} }
