# Clonal operator in Immune Clonal Strategy

I was reading about Immune Clonal Strategy, specifically about Monoclonal operator from Immunity clonal strategies, and it goes as follows:

Here $$a_i$$ is a point and $$a_i = \{ x_1, x_2, \cdots, x_m \}$$.

I do not understand what $$I_i$$ really is, It seems like just copy $$a_i$$ for $$q_i$$ times or something like that, can someone please explain to me what is really happened here?
