Right.

Oh, you tried it, too. Yeah, such notations have infinitely finite possibility! For example, I have not used more powerful letters such as 𠔻, 𠔻, and 𪚥.

Moreover, we have letters which means fish numbers. Using them, we will get powerful notation of natural numbers.
 * 魚 = Fish number version 1
 * 䲆 = Fish number version 2
 * 鱻 = Fish number version 3
 * 䲜 = Fish number version 4
 * and so on...
