On the other hand I found an interesting site where the more well-known ones are grouped together according to graha bhedam and then according to swara bedham .

Example : The Hindolam group ( Swara bedham )
------HindhOlam ( graphic shifts even though I try to juxtapose them

HindhOlam S _ _ G2 _ M1 _ _ D1 _ N2 _ S+
chandhrakauns S _ _ G2 _ M1 _ _ D1 _ _ N3 S+
shudhDha HindhOlam S _ _ G2 _ M1 _ _ _ D2 N2 _ S+
shudhDha dhanyAsi S _ _ G2 _ M1 _ P _ _ N2 _ S+
The concept would be similar to Kauns-ang in Hindustani sangeet : True for Chandrakauns and Shuddha Hindolam , but not true for Shuddha Dhanyasi .
