description | <p>For positive integers <span class="math"><em>m</em>, <em>n</em></span>, <span class="math"><em>K</em><sub><em>m</em>, <em>n</em></sub></span> represents the complete bipartite graph. We name the graph <span class="math"><em>G</em> = <em>K</em><sub><em>m</em>, <em>n</em></sub> ⊙ <em>K</em><sub>2</sub></span> as triangular extension of complete bipartite graph <span class="math"><em>K</em><sub><em>m</em>, <em>n</em></sub></span>, since there is a triangle hanging from every vertex of <span class="math"><em>K</em><sub><em>m</em>, <em>n</em></sub></span>. In this paper we show that <span class="math"><em>G</em></span> is graceful when <span class="math"><em>m</em> = <em>n</em> = 2ℓ</span>, for any integer <span class="math">ℓ</span>.</p> |
