How many gotra
In Jainism, particularly among the Digambara and Śvētāmbara sects, the concept of gotra (clan or lineage) is prominent in the context of Jain lay communities (especially among Jain laity, not ascetics). Traditionally, there are 84 gotras mentioned among the Jain communities, especially the Oswal and Porwal communities. However, the number and names of gotras may vary among different Jain groups and regions.
In the spiritual context, Jain monastic tradition also speaks of gotras in relation to the 24 Tirthankaras, each having a specific gotra (e.g., Ikshvaku, Kasyapa, etc.). But commonly, when people refer to Jain gotras, they mean the 84 traditional clan lineages found among Jain laypeople.
If you are asking about the Tirthankara gotras: Each of the 24 Tirthankaras belonged to a specific royal gotra or dynasty, such as Ikshvaku, Kasyapa, etc.
If you are asking about layperson clan gotras: Traditionally, 84 is the most commonly cited number, but the actual list may differ between communities.
