(r1,r2,r3,g1,g2,g3,d1,d2,d3,n1,n2,n3 with the constraint r2=g1,r3=g2,d2=n1,d3,n2)

As far as i know ( and i invite any corrections) -
carnatic music like most other music systems has 12 notes
but only 7 names (sa ri ga ma pa dha ni) -
and so, position or frequency wise, sa and pa are single, but
the others are two each. sa, 4 notes, then 2 ma (ma1 and ma2) then pa, then 4 notes.
as per the 72 melakarta scheme, a melakarta raga, besides
sa (1st frequency) pa (8th place) and one ma ma1 or ma2 (6th or 7th place)
must have 4 other notes - two between sa and ma and two between pa and next higher sa.
so you can have any 2 of the 4 notes between sa and ma and any 2 of the 4 between pa and high sa.
because it is impractical, difficult and not too pleasant to sing two ri s or two ga s or dha s or ni s
the notes must be called ri ga and dha ni.
you cant have an arohana as sa ri ri ma pa dha ni sa. etc.
but because there are 4 notes and you can take any pair - they will be called ri and ga.
let us suppose the 4 notes to be A B C D and you need any pair -
you can have AB, AC, AD, BC, BD, CD - and remember we call any pair ri and ga.
So A is always ri (ri 1) and D is always ga ( ga 3)
but B can be ga (ga 1) or ri (ri2 or ri 3).
C can be ri (ri 3) or ga (ga 2 or ga 3)
Sorry for that long explanation. dont know if i am clear.
i myself got lost somewhere in the beginning itself.
