Let $\displaystyle \beta = (1 \; 7\; 8)(3 \;10)(6 \;11\; 12)$ in the symmetric group $\displaystyle S_{12}$

Express $\displaystyle \beta$ as a product of transpositions in the form $\displaystyle (1 \; b)$, with $\displaystyle b \in \{ 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 \}$

I can express it as normal transpositions, but not sure how to go about it with the first number only being 1.

Thanks
