Can a magisian have a spell twice in his mental invetory?

Can a magiψian have a spell twice in his mental invetory?

I can’t find the answer in the rules.

I am fairly sure the answer is yes, at least I’ve always played it that way. The inventory is a number of “slots”, you can fill it with anything from your spellbook, in multiples or not.

Yes. A second level magician could have Celestial Music memorized twice.

Thanx!
