I am looking for latex codes for the following characters:

My attempt to use detexify to find the symbols were unsuccessful.

\mathbb{1} does not produce the right symbol.

\documentclass{article}
\usepackage{bbm,graphicx}
\begin{document}
$\mathbbm{1}$\reflectbox{$\mathbbm{1}$}
\end{document}

enter image description here

Alternately, in campa's referenced answer, there is also the dsfont package, giving what looks like a scalable alternative:

\documentclass{article}
\usepackage{dsfont,graphicx}
\begin{document}
$\mathds{1}$\reflectbox{$\mathds{1}$}
\end{document}

    \reflectbox is shorter ;-) – campa Feb 18 '21 at 14:59
  • @campa Thanks. I approach LaTeX like I do physics. I just remember the original equation, F=d(mv)/dt, and the rest proceeds from there. – Steven B. Segletes Feb 18 '21 at 15:04
  • Thank you, this correctly answers my question. The only problem is that I want to use the code for a review for zbmath. I am not sure if they accept graphicx and bbm packages. Let me wait a while before accepting the answer to increase the chance of having new answer. Eventually, I accept the current answer if no new answer comes. – Name Feb 18 '21 at 15:07
  • @Name The \reflectbox is available in several packages, additionally, mathtools, and rotating, if that helps. – Steven B. Segletes Feb 18 '21 at 15:10
  • @Name If you are unable to use the bbm or dsfont packages, a cheap cheat for the digit 1 might be had with $\scalebox{1}[.91]{$1$}\mkern-5.2mu\scalebox{.5}[1]{$1$}$ (feel free to adjust parameters). This, however, still requires graphicx, mathtools, or rotating to accomplish. – Steven B. Segletes Feb 18 '21 at 15:20
  • Please don’t use bbm. It’s a font format from the ’80s designed to be rasterized at one fixed resolution and printed out on paper. But nobody does that any more, and it looks pixelated on screens. The answer that recommended it is nearly ten years old. – Davislor Feb 20 '21 at 01:14
