Comment (by vdelecroix):
And using libgap directly is even faster
{{{
sage: M = m._libgap_()
sage: %timeit M^2
The slowest run took 9.57 times longer than the fastest. This could mean
that an intermediate result is being cached
1000 loops, best of 3: 183 µs per loop
}}}
So, as written in the bottom of the description in #18152, we should wrap
GAP matrices to deal with dense cyclotomics matrices in Sage.
