An equiangular tight frame (ETF) is a d × n matrix that has orthogonal rows and unit-norm columns. ETFs have applications in communications, coding theory and quantum computing. In this paper we investigate type of ETFs that have n + 1 vectors in R n . Also we state the connection between these frames with the complete graphs that containing n + 1 vertices.
