# Spacing between footnotes similar to spacing in footnote

I add line spacing to my main text with \setstretch{1.18} and to footnotes with \setstretch{1.22}. When there are multiple footnotes on a page I of course want the spacing between the last line of one and the first line of the next to be the same as between lines in the same footnote. By eyesight I have more or less achieved this with \setlength{\footnotesep}{.59\baselineskip}.

Is there a way to do this automatically and exactly?

MWE:

\documentclass[11pt,a5paper]{article}
\usepackage{setspace}
\setstretch{1.18}
\setlength{\footnotesep}{.59\baselineskip}
\newcommand{\note}[1]{\footnote{\setstretch{1.22}#1}}
\newcommand{\lorum}{Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Ut purus elit, vestibulum ut, placerat ac, adipiscing vitae, felis. Curabitur dictum gravida mauris.}
\usepackage{lipsum}

\begin{document}
\lorum\note{\lorum}

\lorum\note{\lorum}
\end{document}


Result:

• Just out of curiosity: Why would you want to use anything but singlespacing in the footnotes? – Mico Dec 6 '18 at 16:47
• @Mico Because there needs to be enough space for some mathematical notation that has symbols under the main line. – Casper Dec 6 '18 at 17:03
• In case there are some such mathematical notation, LaTeX will enlarge the spacing automatically. – user156344 Dec 7 '18 at 11:21
• @JouleV Yes, but non-uniformly, which I think is ugly – Casper Dec 7 '18 at 11:23

Just multiply the standard \footnotesep by 1.22:

\documentclass[11pt,a5paper]{article}

\usepackage{setspace}
\setstretch{1.18}
\setlength{\footnotesep}{1.22\footnotesep}
\newcommand{\note}[1]{\footnote{\setstretch{1.22}#1}}

\newcommand{\lorum}{Lorem ipsum dolor sit amet, consectetuer
adipiscing elit. Ut purus elit, vestibulum ut, placerat ac,
adipiscing vitae, felis. Curabitur dictum gravida mauris.}

\begin{document}

\lorum\note{\lorum}

\lorum\note{\lorum}

\end{document}
