The word vargaH वर्गः "group" means a group of letters that have the same position.
This word is not used by /pANini. /pANini says /ku instead of kavarga कवर्ग (see aNuditsav...). But I mention vargaH वर्गः here because later grammarians use it, and many Indians heard about it in school.
The five main /varga are —
ka-vargaH कॱवर्गः or /ku —
ka kha ga gha Ga क ख ग घ ङ
ca-vargaH चॱवर्गः or /cu —
ca cha ja jha Ja च छ ज झ ञ
Ta-vargaH टॱवर्गः or /Tu —
Ta Tha Da Dha Na ट ठ ड ढ ण
ta-vargaH तॱवर्गः or /tu —
ta tha da dha na त थ द ध न
pa-vargaH पॱवर्गः or /pu —
pa pha ba bha ma प फ ब भ म
The letters in the same /varga are /savarNa of each other.
