Description (last modified by )
matrix_mod_pn()
for elements in Eisenstein extensions of Zp
suffers from the same inaccuracy problem as the one described in #13651.
sage: R=Zp(3,3) sage: S.<a>=R[] sage: L.<a>=R.extension(a^2-3) sage: L(3).matrix_mod_pn() [57 0] [ 0 57]
The attached patch fixes this.
