摘要
描述了_n型仿射Weyl群a值为5的A_2×A_(12)~2型左胞腔的个数.并计算出当n=8时,这样的左胞腔个数为8个;当n=9时,这样的左胞腔个数为35个;当n≥10时,左胞腔个数为1/(30)(n^5-20n^4-155n^3+7520n^2-7254n+220240)个.
This article describes the Type Bn affine Weyl group of a value of 5 A2×A(12)^2 left cell number. When n = 8, and calculated This is left cell number 8; When n = 9, such left cell number is 35; When n ≥ 10, left cell number 1/(30)(n^5-20n^4-155n^3+7520n^2-7254n+220240)
