 | | After all, if you have the binary operation of product, then you have ternary operations defined (in 2 ways) by composing this binary operation with itself, as well as quaternary operations defined by composing some more (in 5 ways), and so on. |
 | | Similarly, if you have no operations given at all, then you must have the identity operations. |
 | | Thus, Com has a binary operation, a nullary operation, a ternary relation, a binary relation, and a unary relation, while Lie has a binary operation, a ternary relation, and a binary relation. |
