The Forgotten Matrix (𖡵) is the final number of Episode 50, Season 5, and the first semester of Freddie Fazbear 2024's Numbers 0 to The End of Numbers series, also marking the halfway point of the series. It follows a final explosion that "is so extreme, it generates an Absolutely Everything Black Hole".
This number is also called The Forgotten Realm in its video's concluding statement, but in a response to a comment by Daniel Dixon, Freddie Fazbear 2024 stated that The Forgotten Matrix is the proper name for the number.
Essentially this number is the "Epsilon Nought" of Fictional Googology.
