Are there any descent symmetry tables for character tables of linear structures?
Here they are, finally I found them in some random presentation for a lecture:

$$\begin{array}{c|c} \hline
D_{\infty \mathrm h} &amp; D_\mathrm{2h} \\ \hline
\mathrm{\Sigma_g^+} &amp; \mathrm{A_g} \\
\mathrm{\Sigma_g^-} &amp; \mathrm{B_{1g}} \\
\mathrm{\Pi_g} &amp; \mathrm{B_{2g} + B_{3g}} \\
\mathrm{\Delta_g} &amp; \mathrm{A_{g} + B_{1g}} \\
\mathrm{\Sigma_u^+} &amp; \mathrm{B_{1u}} \\
\mathrm{\Sigma_u^-} &amp; \mathrm{A_u} \\
\mathrm{\Pi_u} &amp; \mathrm{B_{2u} + B_{3u}} \\
\mathrm{\Delta_u} &amp; \mathrm{A_{u} + B_{1u}} \\ \hline
\end{array}$$

$$\begin{array}{c|c} \hline
C_{\infty \mathrm v} &amp; C_\mathrm{2v} \\ \hline
\mathrm{A_1 = \Sigma^+} &amp; \mathrm{A_1} \\
\mathrm{A_2 = \Sigma^-} &amp; \mathrm{A_2} \\
\mathrm{E_1 = \Pi} &amp; \mathrm{B_1 + B_2}\\
\mathrm{E_2 = \Delta} &amp; \mathrm{A_1 + A_2} \\ \hline
\end{array}$$
