## Harish Chandra Rajpoot

Mahoba, India

Harish Chandra Rajpoot is B. Tech. graduate of Mechanical Engineering from Madan Mohan Malaviya University of Technology, Gorakhpur (UP) India. He worked on linear permutations & proposed "Theory of Polygon". He derived the simplest formula for all five platonic solids. He worked to analyse Goldberg polyhedra, Archimedean solids and truncated & stellated polyhedra using his own theory. He authored a book Advanced Geometry, on his research articles, first published by Notion Press, India
