We show that a quotient group of a CI-group with respect to (di)graphs is a CI-group with respect to (di)graphs. In [1,2], Babai and Frankl provided strong constraints on which finite groups could be CI-groups with respect to graphs. As a tool in this program, they proved [1, Lemma 3.5] that a quotient group G/N of a CI-group G with respect to graphs is a CI-group with respect to graphs provide...

Introduction: The use of the latter is available, usually on a paid basis. In practice, five wing indices are most often used to discriminate wings: Ci, Disc.sh., Dbi, Ri, Pci. Due peculiarity structure wings, Ri and especially Disc.sh. determined with significant errors (Std.Err.), which reduces reliability classification as whole. goal work: authors set out find small number identification th...
