This is a bug, for sure (also present in Sage 8.0.beta9)
I've created https://trac.sagemath.org/ticket/23153

Using Sage 7.6 on Ubuntu 16.04.
S = GF(2^4, 'a')
a = S.gen()
G = SL(2, S)
g1 = G([a**2, a**3 + a**2 + a, a + 1, 0])
g2 = G([a, 0, 0, a**3 + 1])
# prints True True
print g1 in G, g2 in G
# Throws a ValueError
print g1 * g2
Here's the exception:

Does typeset output meanwhile work? (I ask as, having e.g. show(x^2) in
a Jupyter notebook

That's not the problem. The problem is how to determine which functions
are actually called.

Thanks for the workaround.

An alternative way of taking quotient avoiding the "is_principal" call
sage: Q = sage.rings.quotient_ring.QuotientRing_generic(R, I, 'a')

Hi,
For more correct context, I'm taking the quotient of the ring of integers
in my worksheet.
f = QQ['t']({16:1, 0:262})
K. = NumberField(f)
R = K.ring_of_integers()
QuotientRing(R, Ideal(263,s+1))
I forgot to include that when simplifying the example.

Do you know about sage.misc.citation.get_systems()?
It's supposed to tell which underlying "system" (library, package, ...)
is used for a particular computation.
One example from a docstring:
sage: from sage.misc.citation import get_systems
sage: get_systems('((x+1)^2).expand()')
['ginac']
