So the odd cohomology (and homology) consists completely of torsion. For finite groups an even stronger result holds: all cohomology is finite: H(BG; R) = 0.

"WebDec 12, 2024 · Studies of their structure are based on cohomology theory. On the other hand, cohomology theory of associative algebras was investigated by Hochschild and other authors [10,11,12,13], but it is not applicable to nonassociative algebras. Cohomology theory of group algebras is an important and great part of algebraic topology. " - Group cohomology physics

WebJul 22, 2024 · This is the reason why all representations of the group's Lie algebra can appear as realizations of symmetries in quantum systems. May be the most famous case is the rotation group S O ( 3), which can be parametrized by The Euler's angles. The true representations of the rotation groups are the integer spin representations.
