 OFFSET 0,9 COMMENTS Prod((1+x^(2*i+1)),i=0..m-1) is the Poincaré polynomial for GL(m). Number of self-conjugate partitions of n into at most 9 parts. Also, number of partitions of n into distinct odd parts not larger than 17. - Álvar Ibeas, Aug 01 2020 REFERENCES H. Weyl, The Classical Groups, Princeton, 1946, see p. 233. LINKS CROSSREFS Cf.
