You can access the source code for eigenvalues_right:
sage: gamma.eigenvectors_right??
There you see that the right eigenvectors are computed by computing the left
eigenvectors of the transpose matrix. So let's check the documentation for
eigenvectors_left
:
sage: gamma.eigenvectors_left??
You can see there an example involving a 2x2 matrix with symbolic entries, followed by the following comment:
This routine calls Maxima and can struggle with even small matrices
with a few variables, such as a `3\times 3` matrix with three variables.
However, if the entries are integers or rationals it can produce exact
values in a reasonable time.
