How can we remove the vertex "e" of Petersen graph and replace with three vertices? enter image description here

I used for drawing Petersen this:

\documentclass[11pt,bezier]{article}

\usepackage{amsmath,amssymb,amsfonts,euscript,graphicx,tikz,tikz-3dplot}

\usepackage{tikz,amsmath,tkz-berge}

\usepackage{caption}

\usetikzlibrary{positioning,arrows,calc}

\begin{tikzpicture}[rotate=90]

\GraphInit[vstyle=Art]

\grPetersen[RA=5, RB=3]

    Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. –  Mar 08 '15 at 05:24

It's not possible with \grPetersen. With these macros you can draw some famous graphs but if you want an incomplete graph you need to use macros from tkz-graph or macros that I use to build the "famous graphs". Here you can draw the sub graph ijfgh then is possible to place the other vertices
