Query: Bethe Algebra using Pure Spinors   We propose a gl(r)-covariant parameterisation of Bethe algebra appearing in
so(2r) integrable models, demonstrate its geometric origin from a fused flag,
and use it to compute the spectrum of periodic rational spin chains, for
various choices of the rank r and Drinfeld polynomials.
