- Since EJAs are commutative, the "right multiplication" matrix is
- also the left multiplication matrix and must be symmetric::
-
- sage: set_random_seed()
- sage: n = ZZ.random_element(1,10).abs()
- sage: J = eja_rn(5)
- sage: J.random_element().matrix().is_symmetric()
- True
- sage: J = eja_ln(5)
- sage: J.random_element().matrix().is_symmetric()
- True
