I meant the number of the repetition of the string \((a+I_a,\ldots,b+I_b)_{(c+I_c,\ldots,d-1)}\) in the right hand side. Is it \(a\)? Or is it the length of \((a,\ldots,b)\)?

For example, which one is the right answer of \((2,3,4)_{5,60}\)?
 * 1) \(((2+I_2,3+I_3,4+I_4)_{(5+I_5,59)},(2+I_2,3+I_3,4+I_4)_{(5+I_5,59)})_{(5+I_5,59)}\)
 * 2) \(((2+I_2,3+I_3,4+I_4)_{(5+I_5,59)},(2+I_2,3+I_3,4+I_4)_{(5+I_5,59)},(2+I_2,3+I_3,4+I_4)_{(5+I_5,59)})_{(5+I_5,59)}\)

I note that in both cases, the strongest function is iterated only twice, and hence the rule does not increase the corresponding ordinal in FGH.
