Hi Lal,
Here is a link to the pali section: https://legacy.suttacentral.net/pi/pp2.1
This is how I have understood all this;
There are two types of sotapanna anugami (Sotapattiphalasacchikiriyaya paṭipanno) based on their dominant faculty. The pragna dominant person is a dhammanusari and a saddha dominant person is a saddhanusari.
There are three types of sotapanna based on the time they will take to attain nibbana; sattakkhattuparamo, kolamkolo and ekabiji.
Sotapanna’s can also be categorised into two based on the dominant faculty they used to attain the sotapanna phala; ditthippatto and saddhavimutto.
I don’t see any inconsistencies in the above.
The only possible issue I have is in the following;
In the explanation of ekabījī, kolaṅkolo, and sattakkhattuparamo the differences for the three are as follows:
So sattakkhattuṃ deve ca mānuse ca sandhāvitvā saṃsaritvā dukkhassantaṃ karoti— ayaṃ vuccati puggalo “sattakkhattuparamo”.
So dve vā tīṇi vā kulāni sandhāvitvā saṃsaritvā dukkhassantaṃ karoti—ayaṃ vuccati puggalo “kolaṃkolo”.
So ekaṃyeva mānusakaṃ bhavaṃ nibbattetvā dukkhassantaṃ karoti—ayaṃ vuccati puggalo “ekabījī”.
Although you said that the number of remaining bhava are precise for these three, the word bhava is only mentioned for ekabiji, while for others it is not mentioned specifically as bhava.
