The default above is ERC-721, which should give 0x80ac58cd. Order does not matter — XOR is commutative — but every function in the interface must be present.
About interface id
ERC-165 lets a contract answer whether it implements a given interface, and the identifier for that interface is simply every function selector in it XORed together. ERC-721 comes out as 0x80ac58cd, ERC-1155 as 0xd9b67a26. Order does not matter because XOR is commutative, but completeness does — miss one function and the identifier is wrong.
