works like it does in the superalgebra, even if we orthonormalize
our basis::
- sage: x = random_eja(field=AA).random_element()
- sage: A = x.subalgebra_generated_by(orthonormalize=True)
- sage: y = A.random_element()
- sage: y.operator()(A.one()) == y
+ sage: x = random_eja(field=AA).random_element() # long time
+ sage: A = x.subalgebra_generated_by(orthonormalize=True) # long time
+ sage: y = A.random_element() # long time
+ sage: y.operator()(A.one()) == y # long time
True
