Isn’t Texas the only state which can legally split itself into 4 or is it 5 states?
Any state can do it with the consent of Congress. Article IV, Section 3:
...no new State shall be formed or erected within the Jurisdiction of any other State; nor any State be formed by the Junction of two or more States, or Parts of States, without the Consent of the Legislatures of the States concerned as well as of the Congress.

Can you explain?
