 //Astron. Astrophys.// **706**, Art. No. L10 (2026).\\
+The molecule was identified through 22 lines, each consisting of an oblated paired of four //a//- and //b//-type transitions with 15 ≤ //J// ≤ 24 and //J// − 5 ≤ //K<sub>c</sub>// ≤ //J//. The rotational temperature was assumed as 9 K. The derived column density is about a factor of 2.7 lower than that of indene and about a factor of 4.7 lower than that of phenalene.\\
