In Jainism, there is no Tirthankar by the name "Viharman." According to Jain tradition, there are 24 Tirthankaras in the current time cycle (Avasarpini), and their names are well-documented in Jain scriptures. Some of the well-known Tirthankaras include Rishabhanatha (Adinath), Mahavira (the 24th Tirthankara), Parshvanatha, and Neminatha, among others.

If you are referring to a specific Tirthankar, please check the spelling or provide more context. If you wish to know about any of the 24 Tirthankaras, feel free to ask!
