I have no idea what you think this function is.

Z526 is https://www.wikifunctions.org/wiki/Z526.

An argument reference is not a Type.

This function should return the input number as-is (see the current implementation of https://www.wikifunctions.org/view/en/Z13637).

That would be the existing Echo function. I don't understand your motivation for creating this function.

Since it is one of sequences listed in https://www.wikifunctions.org/wiki/Wikifunctions:OEIS.

It tells "Error of type Z526" without saying what Z526 is.

Note this also needs fixing: "Error of type <raw ZID without label>" is not something user-friendly.

OK, that's a not great reason, but it's a reason. Either way, as I said, Z801 already exists.

Sure, but that's a distinct task (and already being worked on).
