>To me {fy fancu lo'e namcu lo'e namcu} means "F maps > numbers to numbers".
What is "numbers" other than loi [ro] namcu?
{lo'e namcu} is the number archetype, numbers in general. {loi namcu} is the mass of numbers.
We've talked about this too many times already. It is not very relevant to the fancu thread in any case.
