What are the alternative titles of Thayodhamma Sutta, it's reference number, subsections where it appear in? I am looking Thayodhamma Sutta but could not find it based on the following searchers: accesstoinsight.org search on Google, suttacentral.net search on Google. But references do turn up in a general Google search.

Is it possible to give the Alternative titles of the Sutta, Sutta reference number and link to the Sutta or subsections in which appear in?

I think this Sutta maybe know by a different title on some of these sites which is why it is not found.

A Sotāpanna (Pali) or "He who entered(āpanna) the stream(sota)." ‘stream” is a metaphor for the third of the Four Noble Truths, Noble Eightfold Path. A stream which rigidly flows will not stop until it enters the sea. A Sotapanna has completely entered in to the Eight fold Noble Dhamma Path(Has gained the first magga-phala). So he will surely achieve Arhathood within seven births that are born in human and heavenly happy realms and his spiritual development will not descend.

Attainment

Sotapanna is a person who has eliminated the first three bondages (sanyojanas) from the mind.

Those are,


Strong ego or Personality view(sakkaya dhitti)
Doubt(Wichikiccha)
Wrong rituals and observances/ Superstitions(Seelabbatha paramasa)


Thayodhamma sutta(Abandon three things at a time) explains the skills that should be developed to achieve this supreme task.
