Recognition of Janko groups and some simple $K_4$-groups by the order and one irreducible character degree or character degree graph
In this paper we prove that some Janko groups are uniquely determined by their orders and one irreducible character degree. Also we prove that some finite simple K4-groups are uniquely determined by their character degree graphs and their orders.
