Web4 okt. 2024 · Given a finite p -group D, recall that the size of a minimal set of generators of D is m if, and only if, D : Φ ( D ) = pm, where Φ ( D) is the Frattini subgroup of D. In this note we refer to the number m as the rank of D. If B is a p -block of a finite group G with defect group D then the height-zero characters of B, here denoted by Irr ... WebThe only possibilities are b2 = 1,a b 2 = 1, a or a2 a 2. If b2 = a,a2 b 2 = a, a 2 we find that b b cannot have order 2, so it has order 3. Then 1 = ab 1 = a b or 1 =a2b 1 = a 2 b, both of which are contradictions. Hence b2 = 1 b 2 = 1. Next we determine which element is equal to ba b a. The only possible choices are ab a b or a2b a 2 b.
