What information does Antigone give about Oedipus to Ismene at the beginning of

At the beginning of Sophocles' play "Antigone", Antigone does not share any specific information about Oedipus to her sister Ismene. Instead, they primarily discuss the fate of their two brothers, Polyneices and Eteocles, who have recently died in battle against each other, fighting on opposite sides. Antigone expresses her determination to give Polyneices a proper burial, despite Creon's edict forbidding it, leading to the main conflict of the play. While Oedipus's name comes up briefly, especially with regard to the brothers' conflict, his backstory or specific experiences are not the focus of this conversation.
