Trikakut (त्रिककुट) is a mountain mentioned by Panini (V.4.147).
Mention by Panini
Trikakut (त्रिककुट) is name of a Mountain mentioned by Panini (V.4.147), so called from its three peaks, a name first used in atharvaveda as the source of salve (Anjana), which may be identified with the Sulaiman Mountain, famous as a source of antomony all over Punjab and Sindh, probably same as Sauviranjana. 
V. S. Agrawala mentions Ayudhajivi Sanghas – [p.443]: Panini mentions Ayudhajivi Sanghas by name in sutra V.3.115-117 and in the three Ganas of these sutras, Dāmanayādi, Parśvādi, and Yaudheyādi. The chapter opens with a reference to such Sanghas in the Vāhīka country, the cradle land of martial tribes who cultivated military art as a way of life. Mostly they were Kshatriyas, But Sutra V.3.114 shows that some of them were Brahmans also, e.g. the Gopālavas, and others called Rājanyas, which most likely correspond to those Hill States whose ruling classes designate themselves as Ranas. The Śālaṅkayanas are stated by Kashika to have belonged to the Rajanya class, and they seem to be an ancient community, as even Patanjali mentions them by the name Trika (V.1.58; II.352), probably on account of their League of three states (on the analogy of Shashtha as applied to League of six Trigartas, V.3.116).
