# On the non-existence of $srg(76,21,2,7)$

## TL;DR

This paper proves that a strongly regular graph with parameters (76,21,2,7) cannot exist by employing a novel approach based on the graph's unit vector representation.

## Contribution

It introduces a new non-existence proof for the specific strongly regular graph using unit vector representation methods.

## Key findings

- Proves non-existence of srg(76,21,2,7)
- Introduces a novel proof technique based on vector representations
- Enhances understanding of parameter constraints for strongly regular graphs

## Abstract

We present a new non-existence proof for the strongly regular graph $G$ with parameters $(76,21,2,7)$, using the unit vector representation of the graph.
