本文计算了有限群G的块中不可约的普通特征标和不可约的Brauer特征标的个数，其2-子群PofG（它是块的亏群）上的相关融合系统具有秩为3的交换超焦点子群.
In this paper, we calculate the numbers of irreducible ordinary characters and irreducible Brauer characters in a block of a finite groupG, whose associated fusion system over a 2-subgroupPofG(which is a defect group of the block) has an abelian hyperfocal subgroup of rank 3.
