2020-07-16 23:45:54 +0200	commented answer	Zero Matrix has an Inverse over Finite Field? Thank you, I will try my hand at making a ticket.
2020-07-16 15:43:18 +0200	asked a question	Zero Matrix has an Inverse over Finite Field? The following code `M = Matrix([0], ring=GF(4)) M` Prints "[0]" as expected. The inverse of M clearly does not exist. Even so, running `M.inverse()` does not throw an error, and instead prints "[1]". What's going on here? I am running Sage 8.1. Thanks for the help.
