The working mechanism of RASSCF ALTEr is inconsistent with the manual description

4.2.46.8.1. Optional keywords

ALTEr
This keyword is used to change the ordering of MO in INPORB or JOBOLD. The keyword requires first the number of pairs to be interchanged, followed, for each pair, the symmetry species of the pair and the indices of the two permuting MOs. Here is an example:
ALTEr= 2; 1 4 5; 3 6 8
In this example, 2 pairs of MO will be exchanged: 4 and 5 in symmetry 1 and 6 and 8 in symmetry 3.

Should be ALTEr= 1 1; 1 4 5; 3 6 8 , or ALTEr= 1 0 1; 1 4 5; 3 6 8 ?

I tested a molecule with Ci symmetry have Ag and Au irreducible representation. Orbital exchange works fine with input

alter
1 1
1 x x
2 x x

but raise error with input

alter
2
1 x x
2 x x

MAlter input is wrong.
Wrong orbital to exchange in pair
