[Tex/LaTex] How to create subset with sim symbol

amsmathmath-operatorssymbols

I've been trying to typeset as an operator the symbol ⫇ (\subset on top a \sim), but the following solutions have not been helpful

  • ⫇ does not seem to be listed in symbols-a4.pdf, so detexify does not find it.
  • \limits and \underset puts the tilde (or \sim) too separated from \subset.
  • Using \undertilde looks ugly.

Is any other option to obtain this symbol?

Adapting egreg's solution:

\documentclass{article}
\usepackage{graphicx}

\newcommand\subsetsim{\mathrel{%
  \ooalign{\raise0.2ex\hbox{$\subset$}\cr\hidewidth\raise-0.8ex\hbox{\scalebox{0.9}{$\sim$}}\hidewidth\cr}}}
\begin{document}
\[
  A \subsetsim B
\]
\end{document}

sample output

Adapt the parameters to your likings.
