## Problem

Is there an almost simple but not simple group which is recognizable by the isomorphism type of its Gruenberg-Kegel graph? Note that if a group G is recognizable by the isomorphism type of its Gruenberg- Kegel graph, then G is recognizable by its Gruenberg-Kegel graph, and therefore G is almost simple (P. J. Cameron, N. V. Maslova, J. Algebra, 607 (2022), 186-213). This is Kourovka Notebook Problem \(21.95\).
