# Is there a nice way to make a strikethrough for the square subset character in LaTeX?

I am working on some math that uses the square subset notation. I need a good way to strikethrough the character in LaTeX.

I have tried using the package "cancel" but the strikethrough it produces for the squaresubset character is ugly and looks out of place relative to ⊈ which looks quite nice.

Check the answers to this question: How to look up a math symbol. There are plenty of versions of the symbol you want in the Comprehensive LaTeX Symbol List. –  Alan Munn Jul 25 '11 at 22:59

Did you know that $\mathcal{A}\sqsubseteq\mathcal{B}$? However, $\mathcal{A}\not\sqsubseteq\mathcal{C}$. Also, $\mathcal{C}\not\subseteq\mathcal{D}$.
